Bestselling British author who has written a huge amount of novels for children and teenagers. Most of them are about a specific theme or problem that young people might face. The 1970s magazine ''Jackie'' may or may not have been named after her, depending on who you ask. As well as winning a truckload of awards, she was the Children's Laureate between 2005 and 2007, and was named in the 2008 Honours List.

Several of her books have been adapted for TV.
----
!!Tropes found in her works:

* AbusiveParents - the titular heroine of ''Cookie'' has a father who borders on this, and is certainly abusive to his wife. There's also Elsa's stepfather (nicknamed "Mack the Smack" because he hits her) in ''The Bed and Breakfast Star'', Mary's mother in ''The Diamond Girls'' and Treasure's stepfather in ''Secrets''
** ''The Worry Website'' also has Lisa's dad, her main worry being that she finds out that he's been hitting her mum. She ends up not posting it on the website, instead saying that she's worried about starting to get spots instead.
** Lola Rose's father, who, like Cookie's, was initially abusive to her mom and later to her as well.
** It's implied that Tracy Beaker was abused by her mother's boyfriends before being taken into care.
** Charlie's character Lottie in "The Lottie Project" had an alcoholic abusive father who kept the family in poverty and had recently died.

** Katy's father in ''Waiting For the Sky to Fall'', and Prue's father in ''Love Lessons'', are extremely controlling, demanding and emotionally abusive towards their children.
* AdaptationExpansion - The first season of the TV series ''The Story Of Tracy Beaker'' was more-or-less the first book. But while the second book is about Tracy staying with Cam, the second TV season sees her back at the Dumping Ground. The show then ran for a further three seasons (including one where she gets fostered by Cam ''again''), and ended two years before the third book came out. It has now started again with [[Series/TracyBeakerReturns a series chronicling Tracy returning to the Dumping Ground as a carer,]] and is going to continue with ''The Dumping Ground'' in 2013.
* AdaptationalAttractiveness - In several TV adaptations of the books. Most noticeable is ''Girls in Love'', where chubby, bespectacled Ellie is played by the very pretty Olivia Hallinan; but plain, awkward Dolphin from ''The Illustrated Mum'' and scrappy, untidy Tracy Beaker were also portrayed by rather cute young ladies.
* AdultsAreUseless
* AdultFear: Her books are chock full of it.
* AlliterativeName: Stella Stebbings, Dixie Diamond
* AlphaBitch: Kim in ''Bad Girls'', Louise in ''How to Survive Summer Camp'', Chloe in ''Sleepovers'' and Rhiannon in "Candyfloss" are all examples
** LovableAlphaBitch: Miranda in ''Kiss'', Magda in the ''Girls'' series
* AlwaysVSexy: Vicky from Vicky Angel was meant to be very attractive.
* AndNowForSomethingCompletelyDifferent - ''Hetty Feather'' was Wilson's first historical novel. It can be seen as this trope for her whole career because, with the exception of ''The Worst Thing About My Sister'', all her books released since then have been historical fiction.
** Unless you count ''The Lottie Project'' as being historical, as half of it is set in the present, and half is the diary Charlie wrote for her History project, set in Victorian times.
* AnnoyingYoungerSibling: Many characters qualify with this, such as Vita and Maxie to Em in "Clean Break" and Kenny to Jayni in "Lola Rose". Sometimes the protagonists only see them as this because they are often made to look after them on their own.
** Mostly averted with Pearl to Jodie in "My Sister Jodie".
* AstralProjection - Important to the plot of ''The Other Side'', although it's left open to the reader as to whether it's real or just in the heroine's imagination.
* AttemptedRape - [[spoiler:Magda]] in ''Girls Under Pressure''. Particularly notable since [[spoiler:Nadine]] was almost date-raped in ''Girls In Love''.
* AuthorAvatar: Most of the protagonists in Jacqueline's children's books are this to an extent; they have a tendency to be [[ShrinkingViolet shy]] and/or [[MostWritersAreWriters like writing, reading and making up stories,]] much like Jacqueline herself throughout her childhood.
* BarredFromTheAfterlife - The title character of ''Vicky Angel'', causing her to linger on earth and haunt her best friend. [[spoiler: She is finally granted access to heaven when she saves Jade from being hit by a car as Vicky was.]]
* BirthdayHater - April in ''Dustbin Baby''
* BittersweetEnding - Things generally get better for the protagonists throughout the course of the story, but often they have to acknowledge that life isn't perfect and/or sacrifice something important by the end. In ''Suitcase Kid'', for example, [[spoiler: Andy does end up slightly happier with her situation, but remarks wistfully that she still doesn't fully belong at any of her residences]]. In ''Little Darlings'', Destiny does get to meet her father, but [[spoiler: she's fully aware that the meeting is basically a cynical public relations exercise on his part - she doesn't mind because she at least gets a chance to sing]].
* BlackBestFriend - Naomi in ''The Bed and Breakfast Star''. Cathy from ''Dustbin Baby'' and Magda from the ''Girls'' series become this in the TV adaptations; in the books, both [[RaceLift are described as white.]]
* BrainlessBeauty - Cassie Plumstead
* CantGetAwayWithNuthin - Very common, especially in Tracy Beaker books. An example spanning a whole book is ''Take a Good Look'', where Mary defies her grandma's instructions not to go out alone - and ends up being taken hostage by armed robbers.
* CareerVersusFamily / CareerVersusMan - Touched upon a few times in the ''Girls'' series. In ''Girls Out Late'', Ellie, Nadine and Magda are upset when they discover that their favourite pop star has given up her career to please her boyfriend. In ''Girls in Tears'', Anna's career is a source of friction between her and Ellie's father; and it's mentioned that Ellie's mother gave up a promising career to raise her daughter.
** This comes up in ''Emerald Star'' when [[spoiler:Hetty chooses to go with the circus despite Jem's offer to marry her.]]
* ChildhoodMarriagePromise - In ''Hetty Feather'', Hetty has one with Jem. Sylvie and Carl had one in ''Kiss'', but [[spoiler:Carl later discovers he is gay, leading to heartbreak for Sylvie who had always believed he would grow up to fall in love with her.]]
* CinderellaCircumstances - Lottie in ''The Lottie Project'', who's forced to become a nursemaid to financially support her family despite being just ten years old (she had to lie about her age and pretend to be a teenager.)
** Hetty Feather is also forced to go into domestic servitude to support herself.
** Opal Plumstead has to leave school and work in a sweet factory to support her family after her father is sent to prison.
* CloudCuckoolander - a lot of characters fall into this trope, particularly Marigold in ''The Illustrated Mum'' ([[spoiler: who, it is later revealed, has serious bipolar disorder and has to go into hospital]]) and Allison in ''The Other Side'' ([[spoiler: also heavily implied to be mentally ill.]])
* ComingOutStory: [[spoiler: Kiss becomes this for Carl.]]
* CoolTeacher - Several, one prominent example being Mr Speed in ''The Worry Website''.
** Mr Harrison, the school librarian in ''The Illustrated Mum'' deserves a mention too.
* CosmeticCatastrophe
* CreepyUncle - Lily's former stepfather (the twins' father) in ''Lily Alone'' is a variant of this; she often mentions that she does not like the way he stares at her and makes suggestive comments towards her. Another variant is Jade's dad in Vicky Angel, who seems to have developed an extremely squicky crush on the now dead Vicky. Jade notices and is disgusted by it.
* CuteBruiser - Tracy Beaker, Elsa in ''The Bed and Breakfast Star'', Jude in ''The Diamond Girls'', Gemma in ''Best Friends'', Ruby in ''Double Act'', Treasure in ''Secrets'', Dolphin in ''The Illustrated Mum''.
* DaddysGirl - Floss in ''Candyfloss'', Em in ''Clean Break'' (although he's an adoptive dad), Barbara in ''Deep Blue''. Deconstructed with Jayni in ''Lola Rose'' and Beauty in ''Cookie'', who behave like Daddy's Girls simply because they are afraid of their abusive fathers.
** Mandy in ''Bad Girls'' very much fits this role - even so much as actually calling her father Daddy despite her age. She occasionally seems to subvert this by wishing she had different parents or was adopted, only to then feel terrible and go rushing back to her parents' sides.
** Star in ''The Illustrated Mum'' becomes this when she meets her father for the first time. [[spoiler: It's hinted that he's not the best at commitment, and that he might end up leaving her behind again.]]
* DeathByChildbirth - In ''The Longest Whale Song'', Ella's mother goes into a very dangerous and life-threatening coma after complications from the birth of Ella's baby brother. [[spoiler:The trope is ultimately averted as she wakes at the end of the book.]]
* DepartmentOfChildDisservices - Features in a few books. In ''Dustbin Baby'' they place April in a care home where she is viciously bullied (which the staff don't notice) and where other kids are actively committing crimes. Tracy Beaker is also placed in care at "The Dumping Ground", so-called because it's where kids are "dumped" when no one will adopt them, which woefully lacks funding and resources. In ''The Bed and Breakfast Star'', local authorities house Elsa's family in a "bed and breakfast" hostel that is clearly not suitable for a family with three young children; and won't move Naomi's family out of the hostel even though the damp is aggravating her little brother's asthma.
* DevilInPlainSight - ''Dustbin Baby'' mentions that April was frequently tormented by a girl at the care home where she used to live, with all the carers seemingly blind to this and thinking the girls were best friends, until April pushed the girl down the stairs and put her in hospital.
** Justine in the ''Tracy Beaker'' series
* DistantFinale: The epilogue of ''Queenie'' takes place sixty years after the main events of the story.
* DomesticAbuse - Jayni/Lola's father in ''Lola Rose'', and the titular character's father in ''Cookie''.
* DontSplitUsUp - Lily's motivation in ''Lily Alone''.
** Jayni in ''Lola Rose'', and Star in ''The Illustrated Mum'', refuse to get help when they are in trouble without a responsible adult around (Jayni's mother is in hospital being treated for breast cancer; Star's mother has bipolar disorder and can't take of her children) out of fear of being taken into care and separated from their sibling.
* DoorstopBaby - April of ''Dustbin Baby'', who as the title suggests was actually found abandoned in a bin.
* DownerEnding - Not unheard of, particularly in [[spoiler:''My Sister Jodie'', even if the birth of May adds a note of hope.]] Another book not immune to this was [[spoiler: ''Lily Alone'': whilst the books ends with Lily claiming that "we're all going to be together, very, very soon", just how accurate her statement is is left extremely ambiguous.]]
** Wilson's earlier novels were more prone to the DownerEnding; since she hit the big time with the first ''Tracy Beaker'' book, a BittersweetEnding is more common.
* DrivenToSuicide - April's adoptive mother in ''Dustbin Baby'', Tina in ''Falling Apart'', [[spoiler:Carl in ''Kiss'', though he survives]] and Tanya's mother in ''Bad Girls''.
* DullEyesOfUnhappiness - In ''Dustbin Baby'', April goes to visit the grave of her adoptive mother, whose headstone has a picture of her on her wedding day. April notes how bright her adoptive mother's eyes are in the picture, and sadly reflects that they didn't look at all like that when April knew her.
* EasilyForgiven - Ellie must have a hugely forgiving personality, since she forgives some pretty vicious treatment from best friend Nadine, and forgives [[spoiler:Magda and Russel, her other best friend and boyfriend]] for kissing behind her back at a party.
** Violet forgives Jasmine and Will for their deception disappointingly quickly in ''Midnight''. Although Jasmine clearly did like Violet for her own sake, her desperation to visit Violet's home was all about her desire to [[spoiler: get closer to Will]]. YMMV as to whether or not this makes her worse than Violet's old friends Marnie and Terry, who tried the same thing [[spoiler: (albeit unsuccessfully,)]] without having engaged Violet's feelings.
** A lot of the characters in her books forgive their friends and loved ones extremely easily: Garnet forgives Ruby almost instantaneously for all of her bullying, Tracy treats her mother like an angel despite all the pain she causes her, and the one time Jade ''doesn't'' forgive her best friend Vicky for being horrible to her, [[spoiler: she ''dies.'']] In some cases, the girls have learnt to stand up for themselves by the end of the book, in others, they simply don't.
* {{Expy}} - Almost all the characters in ''Love Lessons'' are Expies of those from an earlier novel of Wilson's called ''Waiting For the Sky to Fall''.
** Hetty Feather has many similarities to Lottie in ''The Lottie Project'', including the historical setting, red hair, outspoken nature and working in domestic service.
* EvenTheGuysWantHim - ''Midnight'': "All the girls at my school are in love with Will. And some of the boys."
* FairytaleMotifs - Violet in ''Midnight'', Ellie in the ''Girls'' series, Mae in ''The Power of the Shade'', Opal in ''Opal Plumstead''
* FatIdiot - Subverted with Biscuits, who is actually pretty clever. Also subverted in ''Vicky Angel'' where Jade initially thinks of Sam as a FatIdiot, but he turns out to be funny, intelligent and kind.
** Played straight in ''Love Lessons'' and ''Waiting for the Sky to Fall'' (see {{Expy}} above) where Grace and Nicola are both overweight and considerably mentally slow, although they're portrayed sympathetically.
** Subverted again with the fat Mr Harrison from ''The Illustrated Mum''; he's always kind to Dolphin and Oliver and even helps to stop them from getting into trouble with their teacher. He's also shown to be quite intelligent.
** And again with Ellie in the ''Girls'' series, who is definitely overweight and actually pretty intelligent (although her common sense is questionable at times).
* FatherIWantToMarryMyBrother - Violet in ''Midnight''. Borders on BigBrotherAttraction when she admits that at age fourteen she still harbours hopes of them living together when they grow up. Will is adopted, but Violet didn't know this for most of her life, and still sees him as a big brother.
* FieryRedhead - Charlie and Lottie in ''The Lottie Project'', Hetty Feather, and Vicky in ''Vicky Angel'' all count.
* ForegoneConclusion - in ''Vicky Angel'', Vicky is still alive in the first chapter or two - but from the title alone, what do you think is going to happen to her?
** In My Sister Jodie, [[spoiler: Jodie dies two chapters from the end]] - but this is given away in some versions of the blurb.
* {{Gayngst}}: Poor, poor [[spoiler: Carl.]]
* GRatedSex - Occurs in some of the author's earlier novels aimed at teens (such as ''Falling Apart'' and ''The Dream Palace''). Usually done in a slightly confusing way whereby a normal scene occurs (such as the couple going for a walk or hanging out in the guy's room) with nothing untoward described, and then the protagonist casually mentions later that sex took place in the middle of the scene.
* HandicappedBadass - Mary in ''Take a Good Look'', a partially sighted teen who [[spoiler:foils an armed robbery.]]
* HugeSchoolgirl - Ellie, who is embarrassed about her weight and large bust. Nadine, who's mentioned as very tall, may also count.
* IDontWantToRuinOurFriendship - At the end of ''Emerald Star'', [[spoiler:Jem tries to propose to Hetty, but she turns him down this way because she knows she can't love him romantically.]]
* IJustWantToBeNormal - Barbara in ''Deep Blue'' has spent her life training to be an Olympic diving champion, and feels that she has missed out on "normal" experiences as a result. This trope causes her to use a minor accident at the pool as an excuse to quit diving so that she can attend parties and hang out with boys like a regular girl of her age.
* IllGirl - Elsie in ''Queenie''.
* ImportantHaircut - in ''Double Act'', Ruby cuts her hair to make her look different from her twin sister.
** Jade also gets a new haircut in Vicky Angel, signifying the beginning of her efforts to break away from Vicky's hold over her and the person she used to be.
* IncompatibleOrientation - Sylvie and [[spoiler:Carl]] in ''Kiss''. In the ''Girls'' series, Ellie has a crush on a handsome guy who turns out to be gay, leading to embarrassment for her when she pretends to her friends that he is her boyfriend Dan (the real Dan being awkward and nerdy.) She and the gay guy do become good friends though.
* IncrediblyLamePun - Elsa is prone to these in ''The Bed and Breakfast Star''
* InnocentInaccurate - Several cases of this. Among the most poignant are April in ''Dustbin Baby'', who [[spoiler:doesn't realise her depressed mother has committed suicide in the bathtub]] and Verity in ''The Cat Mummy'' when [[spoiler: she tries to mummify her dead cat after learning about Egyptian mummies at school, and can't understand why her family is horrified at finding out what she's done]]
** An odd example in ''Little Darlings.'' It's Destiny's ''mum'' who's the innocent one. She met Danny Kilman, the famous rock star she had a crush on, at one of his gigs when she was eighteen, leading to Destiny's conception. Eleven years later she still thinks it was a serious albeit-brief relationship, despite all evidence pointing to it being a one-night stand.
** In ''Love Lessons'', Prue's affair with Mr. Raxberry is exposed when Sarah, a student with an intellectual disability, tells everyone that she saw them kissing. Sarah doesn't understand that this isn't supposed to happen, and even Prue (who is otherwise selfish and aggressive) can't be angry with her.
* JacobMarleyApparel - Averted with Vicky in ''Vicky Angel'', who as a ghost can change clothes and hairstyles any time she likes.
* LimitedSpecialCollectorsUltimateEdition - In ''Midnight'', Violet owns a first edition copy of ''The Smoke Fairy'' by Casper Dream, which is now highly prized by collectors (it is his first published work and only a few copies exist, as it was subsequently banned from sale.) Violet's aware of how valuable it would be, but treasures it so much that she will never sell it.
* LittleMissBadass - Prue in ''Love Lessons'', Tracy Beaker, Tanya in ''Bad Girls'' and ''Dustbin Baby''
* LoveMakesYouCrazy
* LovingAShadow - A few examples:
** Destiny's mother in ''Little Darlings'' didn't really know the father of her daughter, and was caught up in the fantasy she associated with his being a rock star.
** In the first book of the ''Girls'' series, Ellie falls hard for Kevin, an older guy she's seen around town but never really met or spoken to. She later develops a relationship with Dan (a guy her own age) and has to admit that Kevin was a fantasy for her; he's actually gay and nothing like the person she imagined, although they do become friends.
** Marigold in ''The Illustrated Mum'' has idolized Micky as the love of her life for years, but is oblivious to the fact he doesn't care about her and isn't at all the person she thinks he is. After they broke up, she got together with Dolphin's father mostly because he looked a little like Micky and had the same name.
** Sylvie in ''Kiss'' believes she's in love with her friend Carl and that they will get married when they grow up. As they become teenagers, Sylvie clings to her image of him, unable to understand that he's changing as a person and has fallen for a guy.
** Drives the plot of ''Falling Apart''. Tina falls for the older, [[UptownGirl more socially advanced]] Simon and soon convinces herself that he is the love of her life. She is unable to see that he is not the person she thinks he is, and that to him their relationship is just a casual fling. It [[DrivenToSuicide doesn't end well]] when he breaks up with her.
* ManipulativeBastard - Most of the abusive parents. However, special mention goes to Will of ''Midnight''. There's something subtly and deeply troubling about the way he treats Violet that borders on horrific, FreudianExcuse or not. There's little chance that you'll read the section about the blindfold game and not at least suspect that Will's a sadist.
* MarketBasedTitle - ''Elsa, Star of the Shelter'' was changed to ''The Bed and Breakfast Star'' in reprints, to reflect the change in accommodation offered to families like Elsa's.
* [[MayDecemberRomance May September Romance]] - Coral and her boss in ''This Girl'', Prue and Mr Raxberry in ''Love Lessons''. In the ''Girls'' series, this is a source of tension between Ellie's father (in his 50s) and stepmother (late 20s/early 30s.)
* MaybeMagicMaybeMundane - ''The Power of the Shade'' and ''The Other Side'', where it's left open to the reader whether May and Alison really have supernatural powers (although the latter book more strongly implies that Alison uses fantasies of astral projection as a coping mechanism.)
** Before the start of the "Vicky Angel", Wilson states that many people have asked her if Vicky is really there, or if it is just Jade's imagination. She says that "You will have to make up your own mind!"
* MeaningfulName - In ''The Illustrated Mum'', it turns out that Dolphin's name came from the fact that [[spoiler: her father was the one to finally teach her mother to swim. Made all the more touching by the fact Marigold claims not to have remembered much about him.]]
* MeaningfulRename - the end of ''Lola Rose'' implies that Jayni will continue living as Lola, an identity she struggled to live up to for most of the book.
** Hetty Feather has a couple of these, going by the aliases "Sapphire Battersea", "Emerald Greenwich" and "Emerald Star."
* {{Meganekko}} - Ellie in the ''Girls'' series
* MissingMom - ''Hetty Feather'' centres around the heroine, an ostensibly abandoned Victorian girl, trying to find her mother. [[spoiler:She does.]]
** In the ''Girls'' series, it is mentioned that Ellie's low self-esteem is partly due to her mother's death.
** Several of Wilson's other heroines also have dead mothers, including Verity (''The Cat Mummy'') and Ruby and Garnet (''Double Act''.) Tracy Beaker, who was abandoned by her mother, may count as well, and Allison in ''The Other Side'' whose mother is mentally ill and goes into hospital at the start of the book.
* MoralGuardians - Referenced InUniverse in ''Midnight'', where Violet mentions that Casper Dream's first book ("The Smoke Fairy") was recalled because of concerns that it encouraged smoking in children.
* MostWritersAreWriters - Most of the protagonist characters are either aspiring writers or aspiring artists.
* TheMunchausen - Tracy Beaker, sort of. The tall tales she tells are about her mother rather than herself.
* NearDeathClairvoyance - Vicky in ''Vicky Angel''
* NightmareFuelStationAttendant
* NoSympathy - Nadine and Magda often behave this way towards Ellie in the ''Girls'' series. Several sets of parents - particularly Andy's in ''The Suitcase Kid'' and Sunset's in ''Little Darlings'' (though only to Sunset and not her younger siblings) - show a woeful lack of empathy as well.
* NotBloodSiblings - Jem and Hetty
* OverprotectiveDad - Prue's father in ''Love Lessons'', Katherine's father in ''Waiting For the Sky to Fall'', Beauty's father in ''Cookie''
* {{Paparazzi}} - In ''Little Darlings'', Destiny's celebrity dad has been getting negative press attention from them, so decides to use her in a PR stunt to improve his image.
** Referenced in ''Vicky Angel'' where Jade discovers that a newspaper has taken pictures of her without her consent, and run a factually incorrect piece about her as part of the coverage of Vicky's death.
* ParentalBonus - a less light-hearted: a lot of the issues dealt with in the books are subtle enough for the target demographic to miss, but which an older reader will pick up(or suddenly remember in a bout of FridgeBrilliance)
* ParentalFavoritism
* ParentalNeglect - Happens a lot:
** The most obvious example is ''Dustbin Baby'' where April's mother, who had serious depression, could not look after her and left the five or six-year-old April to attempt to cook for herself, do her own washing and get herself to school.
** Tracy Beaker, and Elsie in ''Queenie'', end up being taken into children's homes because they had been left at home alone by their mothers (although in Elsie's case, she's able to go and live with her grandmother.)
** In ''Lily Alone'', Lily's mother is deliberately neglectful and leaves Lily (who is only ten years old) alone at home to take care of her three preschool-aged siblings. She eventually goes on holiday expecting her ex-boyfriend to babysit, without having asked him first and unaware that he is also on holiday. This leaves the children alone at home with the prospect of being stuck by themselves for two weeks.
** Jayni's mother in ''Lola Rose'' leaves her two young children alone while she works a bar job late at night, eventually leaving them for several days when she goes into hospital for an operation (although they are able to trace their estranged aunt, and get help.)
** Marigold in ''The Illustrated Mum'' is a loving mother, but very often ends up neglecting her children because of her bipolar disorder (such as leaving them alone all night while she goes to a rock concert, or simply not being able to cook or take care of them during depressive episodes.)
** Several other stories have very young protagonists who are left to look after younger siblings alone while the parents work long hours or (in ''The Bed and Breakfast Star'') just sleep all day.
* ParentsAsPeople - Generally not a good thing. In ''Lola Rose'', the mother's understandable terror at being diagnosed with breast cancer almost lands her whole family back with her abusive husband, ''The Diamond Girls'' has the protagonist's family in a constant state of upheaval due to their mother frequently changing boyfriends and moving her children to new homes, ''Illustrated Mum'' sees the bipolar disorder of the generally lovable Marigold get her kids into dire straits, and the parents of ''The Suitcase Kid'' use their daughter as little more than an inconvenient chess piece. Used more positively with Cam in ''Tracy Beaker.''
** An early novel that Wilson based on this theme was ''Amber'', in which the title character struggles to lead a normal life in spite of her mother's irresponsible hippy/"groupie" lifestyle.
** In ''Queenie'', Elsie's mother neglected her to go out partying, leading to Elsie being taken to an orphanage and later adopted by her grandmother. When they reunite years later, Elsie's mother hasn't changed a bit and continues to treat her daughter as an inconvenient nuisance to her own career and lifestyle.
* PlayingATree - In ''The Left-Outs'', Joan hopes to shine at her new school by winning a leading role in the school play (''The Pied Piper of Hamelin''); but is humiliated when she's cast as a rat with no lines. She fights back by starting her own drama club and putting on a play with other kids who had been cast as rats or background props.
* PluckyGirl
* PromotionToParent - Sadie in ''The Mum-Minder'', who must take over her ailing mother's childminding duties for a week. Jayni/Lola gets this to some extent in ''Lola Rose'' when her mother goes into hospital, leaving her alone to take care of her little brother.
** Star in ''The Illustrated Mum'' mentions having raised Dolphin for most of her life despite only being three or so years older than her.
* PunnyName - Billy "Biscuits" [=McVitie=], since [=McVitie=] is one of the biggest biscuit-making companies in Britain.
* RaisedAsTheOppositeGender - In ''The Diamond Girls'', the main character's mother tries to raise her new baby girl as a boy; having been convinced while she was pregnant that she would finally have a son this time (she already has four daughters.) She does get found out and agree to stop the charade.
* RaisedByGrandparents - the heroine of ''The Power of the Shade''
** In ''Queenie'', Elsie was raised by her grandmother because her own mother had abandoned Elsie. ''Secrets'' also has Treasure's grandmother take her in after Treasure is beaten by her stepfather.
* ReplacementGoldfish - in ''Midnight'', the heroine's brother [[spoiler:was adopted because he looked exactly like their parents' first baby, who died]]
** In ''The Illustrated Mum'', Marigold tried to replace her first love Micky with [[spoiler:Dolphin's father Michael, who went by "Micky" at time.]] It didn't work out.
* RetCon - Billy "Biscuits" gets a change of surname between ''Buried Alive/Cliffhanger'' (his first appearances) and ''Best Friends'', where he reappears as a main character in a book unrelated to the previous two.
* RomanticTwoGirlFriendship - Vicky and Jade in ''Vicky Angel'' bordered on this, especially with [[spoiler:Vicky as a ghost being jealous of Jade's friendship with Sam.]]
** Violet and Jasmine in ''Midnight'', too; in fact, it wouldn't be difficult to interpret Violet's long, romanticised descriptions of Jasmine as her being in love with her, or at least having a crush.
** Gemma and Alice in ''Best Friends'', although they're around 10 years old and thus would be a [[DownplayedTrope very mild version of the trope]]. The ending, where [[spoiler:they are banned from seeing each other again but Alice's birthday package lets Gemma know that Alice still considers her a best friend]] almost pushes them into StarCrossedLovers territory.
* SadistTeacher - Miss Beckworth in ''The Lottie Project'' [[spoiler: (though by the end it's obvious she's more of a SternTeacher]])
** Also Miss Hill from ''The Illustrated Mum'', who seems to delight in making Dolphin's day that much worse, despite the fact there would be a lot of evidence that Dol had a rough home life and at one point she continues to lecture Dol about the fact she hasn't even washed her face even as Dol is crying.
* SecondLove - Russell for Ellie in the ''Girls'' series. In ''Opal Plumstead'', Opal ends up marrying her second love Sam [[spoiler:after her first, Morgan, is killed during WWI]].
* SelfInsertFic - the heroine of ''The Lottie Project'' writes her school history project as the fictional diary of a Victorian servant, who is a thinly veiled copy of herself. Also, in ''Clean Break'' the protagonist meets a famous children's author named Jenna Williams, clearly intended to represent Wilson.
** In ''Sapphire Battersea'' Hetty, now known as Sapphire Battersea, writes a partly-fictionalised "memoir" of her life under the name Emerald Greenwich.
* SharedUniverse - Implied across several books:
** Garnet from ''Bad Girls'' is mentioned in ''My Sister Jodie''. She and Ruby also reappear as adults in ''The Butterfly Club''.
** Tanya and Pat from ''Bad Girls'' reappear in ''Dustbin Baby'' where Pat turns out to have been April's first foster carer.
** Biscuits from ''Buried Alive'' and ''Cliffhanger'' is a character in ''Best Friends'', where he's Gemma's friend back home after returning from holidays with Tim.
* ShrinkingViolet - Violet in ''Midnight'' (aptly enough), Sylvie in ''Kiss'', Lizzie in ''Lizzie Zipmouth'', Beauty in ''Cookie'', Lolly in ''The Dream Palace'', Pearl in ''My Sister Jodie'', Garnet in ''Double Act'', Bliss in ''Lily Alone'' and several others.
* SiblingYinYang - Violet and Will (''Midnight''), Pearl and Jodie (''My Sister Jodie''), Dolphin and Star (''The Illustrated Mum''), Garnet and Ruby (''Double Act''), Marty and Melissa in ''The Worst Thing About My Sister''. All the sisters in ''The Diamond Girls'' are examples, but particularly Dixie and Rochelle.
* SignatureStyle - Recurring themes in Wilson's books include broken homes, the heroine wanting to be a writer or artist, part of the story being set in a museum or art gallery, and the main character making friends with a social outcast. Wilson also tends to repeatedly use "though" in place of "but".
* SocietyMarchesOn - Due to changes in the law since ''The Bed and Breakfast Star'' was first published, families with children cannot now be housed in bed and breakfast accommodation - in order to avoid them ending up in the sort of plight that Elsa's family faces in the book. However, ''The Bed and Breakfast Star'' remains in print because of its success.
** Wilson has stated in interviews that this is the reason for her decision to switch focus to historical fiction and stop writing books aimed at teenagers.
* SpellMyNameWithAnS - In ''Lola Rose'', Jayni explains that the unusual spelling of her name is because it was chosen as a portmanteau of her parents' names (Jay and Nikki.)
* StacysMom - Mr "Rax" Raxberry in ''Love Lessons'', Coral's employer in ''This Girl''
* StartMyOwn - In ''The Left-Outs'', a group of kids who didn't get speaking parts in the school play decide to put on their own production.
* StepfordSmiler: Lola Rose would act like this in hope of not setting her father off.
* StressVomit: Happens to several characters in several books. Jade from ''Vicky Angel'' throws up whilst waiting for her dying friend in hospital, and Em from ''Clean Break'' is made physically sick by the revelation that [[spoiler: her father is having an affair.]]
* SympatheticPOV - ''Tracy Beaker'' would be a very different story if anyone else was narrating.
* TeacherStudentRomance - Prue and Mr Raxberry in ''Love Lessons''.
* TheFilmOfTheBook - ''Dustbin Baby'' became a made-for-TV movie. Wilson is reportedly in talks for film adaptations of ''Lola Rose'' and/or ''My Sister Jodie''.
* TeenPregnancy - [[spoiler: 16-year-old Martine]] gets pregnant in ''The Diamond Girls.'' In ''Secrets'', one of Treasure's sisters is a teenage mother, and it is hinted that Treasure's mother was a teenager when she had Treasure. April in ''Dustbin Baby'' believes that her mother was a young teenager who could not take care of a baby and was thus driven to abandon April. It is also noted that Jo from "The Lottie Project" became pregnant with Charlie while she was still in school.
* TheGloriousWarOfSisterlyRivalry - Subverted in ''Opal Plumstead''- while Cassie and Opal have a relatively good relationship, they do fall into the same categories: Cassie is the pretty one, and Opal is the smart one.
* ThemeNaming - ''Love Lessons'', where Prudence and Grace are so named because their father liked Victorian-style "virtue" names. In ''Sleepovers'', the main character and her friends form an "Alphabet Club" because their names begin with the first five letters of the alphabet: Amy, Belle, Chloe, Daisy and Emily.
** Also in ''Sleepovers'', Daisy's sister is named Lily, and all the children in Amy's family have names beginning with A.
** In ''Double Act'', not only do Ruby and Garnet get ThemeTwinNaming, but their mother was also called Opal. Their new stepmother is named Rose, so their father opens a store called The Red Bookshop because his girlfriend and daughters are all named after something red.
* ThemeTwinNaming - Ruby and Garnet are both named after red gems.
* ThereAreNoTherapists: Often the case. Although eventually averted in Vicky Angel when Jade is finally given some grief counselling and it is a big help to her.
* TomboyAndGirlyGirl - Gemma and Alice in ''Best Friends'', Treasure and India in ''Secrets'', Ruby and Garnet in ''Double Act'', Lolly and Lynne in ''The Dream Palace'', Marty and Melissa in ''The Worst Thing About My Sister''.
* TraumaticHaircut - Example of sorts in ''How to Survive Summer Camp'', where Stella mentions that she used to have very long hair but got it chopped down to bristle when the punky-looking hairdresser misunderstood her instructions to cut only a small amount.
* UnluckyChildhoodFriend - Sylvie to Carl in ''Kiss'', although they do seem to be PlatonicLifePartners by the ending.
* VerySpecialEpisode
* WackyParentSeriousChild - Marigold and Star in ''The Illustrated Mum'', Sue and Martine in ''The Diamond Girls'', Jay and Amber in ''Amber''.
* WeightWoe - Ellie in the ''Girls'' series, Em in ''Clean Break'' and Barbara in ''Deep Blue'' all struggle with their weight. The heroine usually ends up losing some weight by the end of the book.
* WhereTheresAWillTheresAStickyNote - [[spoiler:Tina]] in ''Falling Apart'' does this when [[spoiler:she tries, but ultimately fails, to commit suicide.]]
* WhyDidYouMakeMeHitYou - Vicky Angel and Cookie.
* WildTeenParty: A few in some of her books 'for older readers', most notably those featured in the ''Girls'' series.
* WithFriendsLikeThese: Violet's friendship with Jasmine, Ellie's friendship with Nadine and Magda, May's friendship with Selina in ''The Power of the Shade''. All instances require the main character to have the patience of a saint as their friends are by turns cruel and stupid. It's not totally incomprehensible why the friendships survive, but it does seem to require a lot of resilience from the gentler/more sensible friend. Subverted in ''Candyfloss'' where Floss falls out with the unpleasant Rhiannon and starts being best friends with a much nicer girl.
** Sadly for the girls, it's justified because most Jacqueline Wison heroines tend to have trouble making even one friend and they generally aren't willing to risk losing them with all the other problems they've got.
*** An example not involving the main character occurs in ''How to Survive Summer Camp'', where Louise clearly could not care less about Karen but Karen continues to idolise and fawn after her.
*** Vicky was extremely controlling towards Jade which actually makes Jade's heartbreak at Vicky's death even more tragic.
* YourCheatingHeart - The source of a lot of the parental divorces that happen in the books. The stepdad in ''Clean Break'' is overheard by his stepdaughter as he plans to leave the family, Andy's parents split after her dad had an affair with Zen and Crystal's mother, and the rock star dad in ''Little Darlings'' has an affair with a much younger woman. Not unheard of among the younger cast either - see ''Girls in Tears'' [[spoiler: with Magda engaged in a passionate make-out session with Ellie's boyfriend]] and ''Falling Apart'' [[spoiler: where Simon's cheating on Tina and subsequently ditching her drives her to attempt suicide.]]
* YoureNotMyFather - The plot of Wilson's first children's novel, ''Nobody's Perfect'', in which a girl who hates her stepfather tries to track down her biological dad. [[spoiler:He turns out to be equally disappointing.]]
** Dolphin does this a little in ''The Illustrated Mum'' with Star's father, Micky, when Marigold encourages Dolphin to accept him as her own dad. Probably justified on the grounds that Micky spent the whole time fussing over Star and ignoring Dolphin and Marigold.
** Ruby and Garnet in ''Double Act'' love to remind Rose that she is not their mother, although both warm to her by the end of the book.
* ZanyScheme - Particularly books aimed at younger children
