-->--'''Hazel Grace Lancaster'''

''The Fault in Our Stars'' is the fourth solo novel by author Creator/JohnGreen, released on January 10th, 2012. The book focuses on a girl named Hazel Grace Lancaster, who is a teenage recluse: her best friends are her parents and her preferred hobby is rereading her favorite book, ''An Imperial Affliction'', over and over. One night at Support Group (her parents' idea, not hers), she meets gorgeous and philosophical Augustus Waters, who piques her curiosity and gets her thinking again about life, adventure...and love. There's only one snag in this budding romance: Hazel and Augustus met at a ''cancer'' support group. Hazel has thyroid cancer and terminal lung tumors, biding their time against perilous drugs, and Augustus is in remission after bone cancer took his leg.

Before the book was released, it reached #1 on the Amazon.com and Barnes & Noble bestseller lists in June 2011, shortly after its title was announced. Barnes & Noble had accidentally released more than a thousand copies prematurely, however, the fandom vowed not to spoil the book for those who had not received copies.

A blog where John answers questions about TFIOS is currently available [[http://onlyifyoufinishedtfios.tumblr.com/ here]] for anyone who has finished reading the book, and [[SeriousBusiness only for people who have finished the book]]. (It is no longer password-protected, although one still runs a high risk of major spoilers.)

A [[TheFilmOfTheBook movie adaptation]], starring Creator/ShaileneWoodley as Hazel and Ansel Elgort as Augustus, was released in June 2014. There's also what could be considered a companion book, ''This Star Won't Go Out'', which is the autobiography of Esther Grace Earl, a young girl with terminal cancer similar to Hazel's. Esther and John Green were friends, and she was the inspiration for--though not the direct basis of--Hazel.

!!Tropes present in ''The Fault In Our Stars'' include:
* AdaptationalAttractiveness: [[spoiler:Peter van Houten is played by Creator/WillemDafoe in the movie, and unsurprisingly, he's more attractive than the fat and spindly Peter in the book]].
* AdaptedOut: [[spoiler:Minor characters like Kaitlyn, Lydia and Gus' sisters are not present in the film. Van Houten gives Augustus' eulogy to Hazel personally, while Isaac fills the slightly comedic relief role. Some other scenes are also cut to improve the flow (and shorten the length) of the film. John Green's cameo as the parent of Jackie, the little girl who wanted to try on Hazel's cannula, was also cut]].
%% * {{Adorkable}}:
%% ** Both Hazel and Augustus. Lampshaded by each other multiple times. A more specific example would be Augustus's reaction to flying on a plane for the very first time.
%% ** Isaac, too.
* AdultFear: Hazel frets about the negative effect that her cancer has on her loved ones, especially her parents. She also discusses how most cancer tropes just limit you to a character who exists for their disease to be romanticized.
** Hazel's parents have witnessed their daughter nearly die in the ICU when she was thirteen, and her mother was sobbing that she would no longer be a mom anymore. Later on, in the novel and movie she screams out in pain and they have to take her to the hospital in the middle of the night, when her dad has to carry her. Hazel is extremely relieved when her mother says [[spoiler:she's looking into social work to help other families going through a similar situation, and that she will always be Hazel's mom no matter what happens.]]
** Meanwhile Gus's parents are also looking out for him, but Gus DrivesLikeCrazy, insists on going on a trip without them [[spoiler:after finding out his cancer has returned]], and [[ArsonMurderAndJaywalking carries around unlit cigarettes]]. We see rather than hear that they try to be optimists, with the motivational posters at his house, while they indulge Gus's wishes like buying a nice suit for him to wear in case he didn't survive his first operation.
%% * TheAlcoholic: [[spoiler:Peter Van Houten]].
* AlternativeForeignThemeSong: The theme song for the Japanese version of the film is [[https://www.youtube.com/watch?v=iLnX9s0EJhU "Lil Infinity"]] by AAA.
* AnAesop: "The ill and the dying aren't saints, they're people." WordOfGod says the book was written as a reaction to the frequent glamorization of illness in the media.
* ArtificialLimbs: Augustus Waters has a prosthetic leg due to his osteosarcoma.
-->"Excellent! You'll find my leg under the coffee table."
* BavarianFireDrill: Gus when he, Hazel, and Isaac egg Isaac's ex-girlfriend Monica's car and are caught by Monica's mom. It works.
--> "Ma'am your daughters car is deservedly being egged by a blind man. Please go inside before we call the police."
* BeCarefulWhatYouWishFor: Discussed by Hazel and Augustus; Hazel had used her wish to go to Disney World and Epcot, but Augustus saved his wish in case he could think of something more meaningful. [[spoiler: He eventually uses it on a trip to Amsterdam with Hazel to meet Peter van Houten.]]
* TheBigDamnKiss: [[spoiler:Hazel and Augustus in front of a crowd of tourists ''in the Anne Frank house'']].
* BittersweetEnding: [[spoiler:Gus reveals to Hazel that his cancer has returned, and he dies just over a week after Hazel and Isaac have a prefuneral for him. The book ends with Hazel reading a eulogy that Augustus made for her, talking about how getting hurt in this world is inevitable, but we do get to choose whom we allow to hurt us, and that he is happy with his choice and wishes Hazel likes her choice too. The book ends with her saying, "I do."]]
* BlackComedy: In spades.
** Hazel and Augustus joke about how Augustus is so handsome he literally blinded Isaac and "took Hazel's breath away".
** Isaac's eulogy for [[spoiler:Augustus]] at the "prefuneral" also counts.
* BrokenPedestal: Both Augustus Waters and Hazel Grace love and are obsessed with the book ''An Imperial Affliction'' by Peter Van Houten. Augustus uses his one wish to take Hazel to meet Van Houten in Amsterdam. Unfortunately [[spoiler:he turns out to be a total cynical Jerkass, not the wise and poetic writer they'd imagined him to be when they read the book. This is because he lost his daughter to cancer, and it is implied that Hazel painfully reminds him so much of his beloved daughter]].
* CharacterShilling: Hazel's description of Augustus Waters, from the very first time she meets him, is pretty glowing, focusing on his good looks, charisma, and the connection they have in conversation, compared to her descriptions of other people (which tend to be affectionate, but don't gloss over flaws). This ends up fading away as she gets to know him, even though she falls in love with him (and he with her) she gets to see his flaws in greater detail.
* CompanionCube: Hazel named her oxygen tank "Philip," and treats "him" like an annoying pet.
* CompleteTheQuoteTitle: The title is {{quote mine}}d from [[Creator/WilliamShakespeare Shakespeare]]'s "The fault, dear Brutus, is not in our stars but in ourselves." Quoth Creator/JohnGreen, "Which is an easy thing to say if you're, like, you know, Shakespeare or a Roman nobleman, but in the broad sense, I don't know that I agree with Shakespeare a hundred percent." Diseases, especially diseases like cancer, rarely come to affect people who "deserve" it. It's really very random. And cancer is what really serves as the most negative influence on the characters' lives, so the fault did indeed lie in their stars.
* CreatorCameo: Creator/JohnGreen was supposed to play the father (it was a [[GenderFlip mother]] in the book) whose child wanted to try on Hazel's cannula, but the scene was cut.
* DangerTakesABackSeat: [[spoiler:Peter Van Houten scares Hazel when he pops up in the back of her parents' van]].
* DarkestHour: Once [[spoiler:Gus reveals to Hazel that his cancer has returned]], you have a saddening feeling that it's going to be a downward spiral from that point. [[spoiler:[[TearJerker And it]] [[DiabolusExMachina is]].]]
* DeadManWriting: Hazel and Lidewij track down [[spoiler:Augustus' last letter to Van Houten, which turns out not to be the sequel to ''An Imperial Affliction'' but his eulogy for Hazel]].
%% * DeadpanSnarker: [[DisabledSnarker Hazel, Augustus, Isaac]], and Hazel's mom, sometimes. [[spoiler:And Peter Van Houten]].
%% * DeathByNewberyMedal: [[spoiler:An achingly clear example of this trope, up to and including Gus's demise.]]
* DelusionsOfEloquence: Augustus and Hazel are borderline cases--they get some of their longer and/or rarer and/or archaic words right and then misuse "transmit" or "soliloquy", for just two examples.
* DestructoNookie: Averted and lampshaded when [[spoiler:Hazel and Gus have sex, with Hazel commenting that "no headboards were broken", seemingly as a TakeThat to ''Literature/{{Twilight}}''.]]
%% * DisabledLoveInterest: Augustus, in Hazel's view. See ArtificialLimbs.
%% * DisabledSnarker:
%% ** Hazel and Augustus make for a snarky couple.
%% ** Isaac is pretty snarky too, especially after his surgery.
* DistractedByTheSexy: [[GoodBadGirl Kaitlyn]] loses track of the conversation just from the ''thought'' of Augustus.
-->'''Kaitlyn:''' Oh, my God. I've seen him at parties. The things I would do to that boy. I mean, not now that I know you're interested in him. But, oh, sweet holy Lord, I would ride that one-legged pony all the way around the corral.
-->'''Hazel:''' Kaitlyn.
-->'''Kaitlyn:''' Sorry. Do you think you'd have to be on top?
-->'''Hazel:''' Kaitlyn.
-->'''Kaitlyn:''' What were we talking about?
* DoorStopper: Not the book itself (a modest 300 pages, hardcover), but InUniverse, ''An Imperial Affliction'' is stated to be over six hundred pages long.
* DrivesLikeCrazy: Augustus, due in part to his having a prosthetic right leg that prevents him from feeling the subtleties in pressure needed for non-jerky driving experiences. Hazel suspects that the examiner who licensed him (on the third try) only passed him as a "Cancer Perk".
* DyingMomentOfAwesome: Augustus Waters wishes to die this way, but cannot due to his cancer.
* {{Egging}}: Hazel and Augustus help Isaac throw eggs at his ex-girlfriend's car. They're caught by her mum.
* FanDisillusionment: After Hazel and Gus go to Amsterdam to meet Peter van Houton and he treats them poorly and says awful things. [[spoiler:When he shows up at Gus's funeral he's softened a bit, acknowledging the reason why he was so negative- he had a daughter die of cancer]].
* FandomSpecificPlot: A brief reference to "condomy difficulties" during TheirFirstTime has resulted in a good number of fics where [[spoiler: Gus leaves Hazel SomeoneToRememberHimBy]].
* FictionalCounterpart:
** "The Genie Foundation" standing in for [[http://www.wish.org Make-A-Wish]], perhaps because the (older teenage) characters describe going to [[Ride/DisneyThemeParks Disney World]] as wasting your Wish and proceed to [[spoiler:lose their virginity with one another]] on their trip.
** Also, Free Catch All for Craigslist.
* FictionalDocument: The book features ''An Imperial Affliction'' as well as ''The Price of Dawn'' and the following sequels. The epigraph is from ''An Imperial Affliction'', as a reference to ''Literature/TheGreatGatsby'', whose epigraph is also from another fictional book.
* TheFilmOfTheBook: Released in June 2014.
* FluffyCloudHeaven: Gus says he doesn't believe in this, but does say he believes in "Something".
* FollowTheLeader: All of Creator/JohnGreen's earlier works were rereleased with covers incorporating design elements from this books' cover.
* {{Foreshadowing}}: When Hazel, Gus, and Hazel's mom are on the plane, it's mentioned that Hazel and Gus pushed the play button on their movie simultaneously, but Gus's movie started before's Hazel did. [[spoiler:This foreshadows that Gus dies later in the book: just like his movie starts first, his movie, i.e. his life, ends first]].
* FreestateAmsterdam: Mostly averted (Creator/JohnGreen ''really'' likes Amsterdam and goes whenever chance he gets), although the 16-year-old protagonists are served champagne in a restaurant quite openly. Which, at the time the book came out, was perfectly legal under Dutch law.
-->'''Dutch Cabdriver''':Some tourists think Amsterdam is a city of sin, but in truth it is a city of freedom. And in freedom, most people find sin.
* FunnyBackgroundEvent: Isaac [[spoiler:beating the crap out of Gus' trophies and egging Monica's car, both of which happen during Gus and Hazel's heart-to-hearts]].
* GallowsHumor: Hazel, Augustus and Isaac are as full of this as you would expect terminally ill teenagers to be. One particular gem:
--> '''Hazel:''' It's primarily his hotness.
--> '''Gus:''' It can be sort of blinding.
--> '''Hazel:''' It actually did blind our friend Isaac.
--> '''Gus:''' Terrible tragedy, that. But can I help my own deadly beauty?
--> '''Hazel:''' You cannot.
--> '''Gus:''' It is my burden, this beautiful face.
--> '''Hazel:''' Not to mention your body.
--> '''Gus:''' Seriously, don't ever get me started on my hot bod. You don't want to see me naked, Dave. Seeing me naked actually took Hazel Grace's breath away. ''*He nods toward Hazel's oxygen tank*''
* GetOut: [[spoiler:Hazel yells this at Van Houten when he gets into her car to try and talk to her]].
* GettingCrapPastTheRadar: The lyrics to Afasi och Filthy's [[http://lyricstranslate.com/en/bomfalleralla-bomfalleralla.html "Boomfalleralla"]] would probably be enough to bump the movie up to an R rating by itself, if it was not in undubbed [[BilingualBonus Swedish]]. The crap also got past all of the characters in the novel and film, none of whom speaks Swedish. It may be a [[RealitySubtext reference]] to John Green's experience in Dutch department stores, [[https://www.youtube.com/watch?v=RL96ckeyfVo which have a tendency to play hardcore English Gangsta Rap as background music]].
* GlassEye:
** Isaac has one at the beginning of the book, as a result of a rare form of eye cancer. The eye itself isn't really mentioned except as part of his description.
%% ** Anna's mother in ''An Imperial Affliction''.
* AGoodNameForARockBand: The Hectic Glow, a band "so beautifully underground that they don't even exist".
* HarsherInHindsight: InUniverse, [[spoiler: Van Houten insults Augustus' intelligence by saying his cancer must have spread to his brain. A KickTheDog moment on its own, but then Gus later reveals that his cancer did in fact return and has spread to the rest of his body.]]
%% * HeroicBSOD: Hazel has a [[DeathIsASadThing very understandable]] one after [[spoiler: Gus dies]]. And then, of course, poor Isaac had one after [[spoiler: going blind ''and'' being dumped by Monica.]]
* IllGirl:
** Hazel was diagnosed with Stage IV thyroid cancer at age 13, with metastasized tumors in her lungs. This is known from the [[FirstEpisodeSpoiler opening chapter]]. She plays this role to her would-be suitor, the {{Adorkable}} Augustus, who was once quite ill himself and thus able to understand her plight. [[spoiler:Then, the roles are [[InvertedTrope rather cruelly flipped]] as Augustus's cancer returns with a vengeance, making him the illboy and Hazel his (comparatively) healthy comforter during his last days. Notable in that '''both''' characters are technically ill the whole time; Hazel ultimately winds up being merely ''less'' ill than her rapidly-dying boyfriend]].
** Other examples include Caroline Mathers, [[spoiler:Peter Van Houten's late daughter]], and all the other girls at support group, obviously.
* InformedAbility: The book has this with its main characters. Hazel and Gus are both said to be very mature, intellectual and deep yet they behave immaturely more often than not and their "deep" words and thoughts tend to be morbid and existentialist, but not particularly varied or profound. Could be intentional, though, if the author was going for teenagers thinking they are more mature and deep than they really are.
* InspirationallyDisadvantaged: Isaac [[LampshadedTrope lampshades]] this after he becomes blind by jokingly saying, "come over here so I can examine your face with my hands and see deeper into your soul than a sighted person ever could."
* InsufferableGenius: Peter Van Houten is an extremely intelligent but deeply unpleasant man who deliberately speaks in complex philosophical dilemmas and advanced math problems for the sole purpose of annoying people.
%% * {{Jerkass}}: [[spoiler:Van Houten, by his own admission]]. Though there may be hope for him after all. Maybe.
* JumpingOnAGrenade: Augustus enjoys doing this in video games to save the fictional schoolchildren. In a more poetic sense, [[spoiler:when Hazel doesn't want him to love her because she is a "grenade" and her death will hurt him, he does anyway]].
* KendoTeamCaptain: Augustus was a star of the freshman basketball team (in Indiana, where basketball is king) prior to losing a leg to cancer.
* KilledMidSentence: Apparently happens to Anna, the protagonist of the fictional story "An Imperial Affliction", as the story-within-a-story "ends right in the middle of a --"
* LaughOfLove: Hazel and Augustus tend to do this quite frequently around each other, [[spoiler:at least until Augustus' condition worsens, eventually resulting in his death.]]
* LiteraryAllusionTitle:
** The title refers to a line from Creator/WilliamShakespeare's ''Theatre/JuliusCaesar'': "The fault, dear Brutus, is not in our stars, but in ourselves, that we are underlings."
** In-universe, ''An Imperial Affliction'' is named for a phrase in the Emily Dickinson poem "There's a certain slant of light".
* LittlestCancerPatient: The book subverts this to hell and back. The three main protagonists, Hazel, Gus, and Isaac all have some form of cancer, but they do not exist to tug at heartstrings. Hazel especially calls out all the cancer cliches that exist within this trope.
* ManicPixieDreamGirl: Subverted with Augustus Waters being mistaken for a Manic Pixie Dream ''Boy'' but later proving not to be one. He professes his love to Hazel through contrived, rehearsed outings, complete with memorized "soliloquies" (monologues) and "metaphorically-resonant" sandwiches, but the conviction of their love only feels "real" and "true" when the two of them see through the others' cracks during their trip to Amsterdam, mainly after [[spoiler:he reveals to her that he's terminally ill again]].
* MayflyDecemberRomance: Played with, on the scale of an average human lifespan. Hazel, the sixteen-year-old protagonist, diagnosed with terminal cancer, has an uncertain number of years to left to live, but probably not many. Then she meets and falls in love with a seventeen-year-old Augustus, who is well into remission and will likely live a normal number of years. [[spoiler:However, Augustus' cancer recurs, every reader's heart breaks, and Hazel is the one left behind by a lover's death]].
* MeaningfulFuneral: Subverted and played straight. [[spoiler:Augustus]], upon learning he is dying, asks [[spoiler:his]] two closest friends to read their eulogies at a memorial service before [[spoiler:he]] actually dies, leading to a highly personal Meaningful Funeral. [[spoiler:His]] actual funeral, by contrast, consists mostly of platitudes said by more distant acquaintances, although even then, there are a few moments of genuine connection.
* MeaningfulName:
** Lidewij Vliegenthart was supposedly named for Lidewij and Sanne Vliegenthart--two Dutch nerdfighters. Sanne's channel is [[http://www.youtube.com/user/booksandquills/ here]].
** Isaac, who has to get a surgery that causes him to go blind in order to get rid of his cancer, is named after the Biblical Isaac, who also went blind. ("Isaac" also sounds like "eye-sick", though Creator/JohnGreen said this was more a happy accident. "I'm not that punny.")
** [[WordOfGod John himself has confirmed]] that he came up with Hazel's name because hazel is an in-between color and she has an in-between life.
* MenDontCry:
** Averted. Hazel's father bursts into tears in almost every scene he's in. But no one ever makes a negative remark about it.
%% ** Averted with [[spoiler:Gus]] on a couple of occasions too.
%% ** And [[spoiler:Isaac, when Monica breaks up with him]].
* MiseryPoker: Forms rather large (but unspoken) part of the Cancer Support Group experience. People with more serious cancers tend to get more respect automatically, and people with "lesser" forms of cancer (like appendicial cancer) are somewhat looked down upon.
* MoodWhiplash: [[spoiler:The day after Hazel and Augustus share their first kiss and make love, Augustus reveals that his cancer has returned and metastasized]].
%% * MustNotDieAVirgin: [[spoiler:Gus says, "I'm gonna die a virgin," but then later in the story he and Hazel have sex for the first and last time, thus assuring that this never happens]].
* MyFriendsAndZoidberg: Mr. Lancaster's airport sign reads MY BEAUTIFUL FAMILY (AND GUS).
%% * NerdsAreSexy: One of Augustus's main reasons for pursuing Hazel.
* NoEnding: Occurs in-universe. The main charactersí favorite book ends mid-sentence, leaving several plot lines unresolved, and one subplot of the novel deals with the characters trying to find out from the author what happened to the characters.
* OhAndXDies: PlayedWith. The main character, Hazel, opens the book by telling us that her cancer has never been anything but terminal. At the end of the book, [[spoiler:she's still alive, but her boyfriend has died of his cancer, which had been in remission]].
* ParentsAsPeople: Hazel's parents are shown to be very loving and supportive of her but also have their obvious frustrations with the burden her illness has put on their personal lives.
* PopUpTexting: The film version did this, with sketchy "hand drawn" bubbles popping up whenever main characters August and Hazel text each other. They come across as a sketch of iPhone text bubbles.
%% * PrecisionFStrike: Hazel gives Van Houten one of these before storming out of his living room in the movie.
* RealityIsUnrealistic: A few people who reviewed the movie suggested that it was Hollywood-ized to some degree due to [[spoiler:Augustus]]'s chemo not resulting in any hair loss, but the writers did their research and the type of chemo that character would be on in their situation wouldn't result in any hair loss.
%% * ReclusiveArtist: Peter Van Houten is an InUniverse example, much to Hazel's dismay.
* RefugeInAudacity: Gus' speech to Monica's mom after [[spoiler:she catches him, Hazel, and Isaac egging Monica's car, which actually succeeds in getting her to leave them alone to finish their vandalism]].
-->"[[spoiler:Ma'am, your daughter's car has just been deservedly egged by a blind man. Please close the door and go back inside or we'll be forced to call the police]]."
* ReplacementGoldfish: Considering how Hazel says her and Caroline's "cancer selves" could be sisters, Augustus's determination to get to know her as soon as he sees her (insisting she come to his house to watch a movie ''right then'' without actually ''asking'' her or considering that she might have other plans), and his giving her his Wish, essentially his most valuable possession, a mere ''two and a half weeks'' after meeting her, it really sounds like Hazel is Augustus's for Caroline, at least at the beginning of their relationship.
* RuleOfSymbolism: Green has this to say about the book's final sentence ([[spoiler:"I do"]]), which he sees as marital symbolism.
-->"Shakespeare's comedies end in marriage and his tragedies end in death, and I was rather fond of the idea that [[spoiler:my book could end (symbolically, at least) in both.]]"
* RunningGag:
** The books based on Gus's favorite video game. Count how many times "Max Mayhem" is brought up after Hazel reads them.
** ''Series/AmericasNextTopModel''.
* ScrewDestiny: In Norway, the book's title has been translated as ''Fuck Fate'', which [[http://fishingboatproceeds.tumblr.com/post/86606723303/how-is-it-that-the-english-title-for-tfios-is-beautiful John Green finds to be a]] {{Woolseyism}}.
* ShrugOfGod: [[spoiler:Van Houten's InUniverse reaction when Hazel and Angustus ask Van Houten what happened to the characters of ''An Imperial Affliction'' and he tells them he doesn't know]].
* ShoutOut:
** At one point Augustus muses that it would be awesome to fly in a super-fast jet that could follow the sun. John's admitted to being a fan of ''WesternAnimation/PhineasAndFerb'' and this was the plot of their first special.
** "Funky Bones" is located at Indianapolis Museum of Art, where Sarah Urist Green, aka [[WebVideo/VlogBrothers The Yeti]], is Curator of Contemporary Collections. The author's wife had a major hand in bringing the sculpture to Indy.
** Hazel and Augustus watch ''Film/VForVendetta'' the first time she goes to his house.
** ShoutOut/ToShakespeare: The title comes from a line in ''Theatre/JuliusCaesar'' Act I, Scene II.
* SignatureLine: "I fell in love the way you fall asleep: slowly, and then all at once."
* SoBeautifulItsACurse: PlayedForLaughs in this exchange:
-->'''Augustus:''' But can I help my own deadly beauty?
-->'''Hazel:''' You cannot.
-->'''Augustus:''' It is my burden, this beautiful face.
* SmokingIsCool: Gus and his pack of "metaphorically resonant" cigarettes, although he just enjoys holding them in his mouth unlit (they're cancer survivors, not suicidal). Hazel calls him on it the first time she sees him do it. She's especially offended because she already has breathing problems and is on oxygen due to her lung tumors.
%% * StarCrossedLovers: Hazel refers to Augustus and herself as this several times, most notably in her [[spoiler:eulogy at the prefuneral]].
* StealthPun: The "blinding" of Isaac. Unintended, according to Creator/JohnGreen.
* StrictlyFormula: This novel, like Creator/JohnGreenís other books is about a nerdy, highly intelligent teenage boy who has his eye on a quirky, mysterious girl, eventually going on a RoadTrip where he has a mind-blowing revelation about life. However it does reverses the roles, telling it from the quirky girl's perspective as she falls in love with the nerdy TeenGenius who is fawning over her.
* TakeOurWordForIt: Hazel and Augustus agree that "An Imperial Affliction" is the one book that describes what it's really like to have cancer, therefore the book means a lot to them. But we, the readers, only get a dim idea of the plot, a few characters, and the line "Pain demands to be felt." Oh, it's also a DoorStopper.
* TakeThat:
** When Hazel describes [[spoiler:having sex with Augustus for the first time, she mentions that "[[Literature/{{Twilight}} no headboards were broken]]"]].
** The entire book, as well as ''An Imperial Affliction'', is designed to be one big TakeThat to the {{Glurge}} and [[TastesLikeDiabetes sugar]] that [[LittlestCancerPatient most]] [[TheTopicOfCancer cancer]] stories are filled with.
** The film added an opening voiceover in which Hazel disparages the sort of movie in which "[[Film/SayAnything everything is fixed with a Peter Gabriel song]]".
* TeenGenius: Like many other Creator/JohnGreen characters, Hazel and Augustus are insanely philosophical and verbally articulate for their age. Notably, though, [[DelusionsOfEloquence they do get a lot of things wrong]]. For example, Hazel misunderstands relativity, statistics, and the concept of infinity, and Gus says "soliloquy" when he means "monologue". [[WordOfGod According to the author]], this was on purpose, to show that even though they're very intelligent, they're still young and inexperienced.
* ThisIsAWorkOfFiction: In the Author's Note:
-->"This is not so much an author's note as an author's reminder of what was printed in small type a few pages ago: This book is a work of fiction. I made it up."
* ThrowingOutTheScript: Augustus, Hazel and Isaac hold [[spoiler:a "pre-funeral" for one another, where they've written quite unconventional eulogies that they, to each otherís appreciation, read aloud]]. However, at [[spoiler:Augustus actual funeral, Hazel gives Augustus parents a glance before she's about to read that same eulogy she wrote for his pre-funeral again and changes her mind (even though she doesn't actually believe in any of the things she ends up saying instead) since, she states in the voice-over, "Funerals are not for the dead. They're for the living".]]
* TooGoodForThisSinfulEarth:
** Augustus alludes to this, saying, "Like, are you familiar with the trope of the stoic and determined cancer victim who heroically fights her cancer with inhuman strength and never complains or stops smiling even at the very end, ''et cetera''?"
** [[spoiler:"According to the conventions of this genre, he kept his sense of humor until the end, did not for a moment waver in his courage, and his spirit soared like an indomitable eagle until the world itself could not contain his joyous soul. But this was the truth..."]]
* TheTopicOfCancer: Inverted: Both of the main protagonists (and half of the supporting cast) have cancer. They all speak of their condition with a blase-ness that only terminal cancer patients can muster. And people who try to sentimentalize or go emotionally overboard over the condition are heartily mocked.
* ToplessnessFromTheBack: A lingering shot of Hazel in this state after Gus takes off her bra is the most raunchy that the film's sex scene gets.
* TraumaSwing: Gus is so attuned to the traumatic symbolism of Hazel's depressing old swing set that he helps her sell it on the internet.
* WhamLine:
** [[spoiler:"Just before you went into the ICU, I started to feel this ache in my hip."]]
** [[spoiler:"Augustus Waters died eight days after his prefuneral."]] No matter how obvious or predictable it is that it's coming, it still hurts like hell.
* WhatHappenedToTheMouse:
** In-universe: The main characters love a CutShort novel and want to know what happened to, amongst other things, the pet hamster.
** Ironically, the same thing happened to Creator/JohnGreen by readers of the actual novel, even after explaining in an authorís note in the novel and several times [[http://onlyifyoufinishedtfios.tumblr.com/ on this blog]] that he doesnít know anything more about the plot or characters than that which is contained in the book. Effectively, he knows exactly no more and no less than his readers. Even when they don't believe him.
* WriterOnBoard: Creator/JohnGreen has admitted Van Houten's pro-DeathOfTheAuthor views are essentially his own (though he hopes he's less of a {{Jerkass}} about it).
* WritersCannotDoMath: While she's right that some infinities are larger than other infinities, Hazel incorrectly believes that the infinite set between zero and two is larger than the infinite set between zero and one. However, WordOfGod states that it was intentional, as he didnít want his characters to always be right.[[note]]This is assuming we're looking at the cardinality of the sets. For some MindScrew, consider that using different definitions of infinity can lead to the statement being true, wrong, and backwards all the the same time. Two sets of infinity can be the same, just as easy as one can be bigger than the other. 0 to 1 could be the same, smaller, or ''bigger'' than 0 to 2. It really depends on what definition of infinity you use and who you ask.[[/note]]
