The ''Kiki Strike'' books are a series of action/mystery/adventure books written for young adults by Kirsten Miller. They center on Ananka Fishbein, a teenage bookworm whose curiosity leads her to discover an underground city with a troop of delinquent Girl Scouts, known as the Irregulars.

There are three books out: ''Kiki Strike: Inside the Shadow City'' (2006), ''Kiki Strike: The Empress' Tomb'' (2007), and ''Kiki Strike: The Darkness Dwellers'' (2013).

!!Tropes Used:

* AcquiredPoisonImmunity: One of Dee Dee's concoctions gives you this.
* BadassBookworm: Anaka eventually grows into this.
* BeautifulAllAlong
* BeneathTheEarth: The Shadow City, of course. The [[http://www.kikistrike.com/ website]] demonstrates all the research that went into making it viable. The third book moves to the catacombs of Paris.
* BigApplesauce
* BoardingSchoolOfHorrors: In the second book, Ananka's parents threaten to send her to one if she doesn't get her grades up. [[spoiler:It's a lie to scare her into doing it]]. In the third book, Amelia Beauregard's Institute is notorious for destroying a girl's individuality.
* BrilliantButLazy: Ananka.
* BrutalHonesty: Why the girls often think Oona is rude.
** Leads to BigEgoHiddenDepths: Oona honestly didn't realize that people see her as mean and rude until Ananka pointed it out to her.
* CuteBruiser: Kiki herself.
* CuteClumsyGirl: Dee Dee Morlock.
* DeadpanSnarker: Oona Wong.
* DefrostingIceQueen: Luz Lopez.
* {{Delinquents}}: Luz makes illegal weapons, Oona's a forger and master computer hacker, and Kiki is a thief. And they're Girl Scouts.
* EverybodyKnewAlready: [[spoiler:In the third book, Ananka finds herself falling in love with Betty's boyfriend, Kaspar--or, at least, [[LookingForLoveInAllTheWrongPlaces she ''thought'' she was falling in love with him]]. In the end, the other Irregulars reveal that they already knew she had a crush on him, as she didn't really do anything to hide it (even Betty knew, but she was okay with it). Ananka eventually gets over her crush on Kaspar and presumably starts going out with a guy named Hector, who, as described by Oona and Iris, the youngest of the Irregulars, is essentially a male version of Ananka]].
* EverythingsBetterWithPrincesses: In both the literal and figurative (high school social status) sense. The first book notes that there are so many deposed Eastern European princesses that no New York high-class social circle would be complete without one.
* {{Evil Prince}}ss: Sidonia.
* TheFellowshipHasEnded: In the first book, after solving the drug-smuggling ring in the Shadow City, the gang sells the patent to an invention they use to explore the city, split the profits, and (for the most part) go their separate ways. Kiki later reunites them to help her stop Sidonia.
* FieryRedhead: Luz Lopez.
* [[GirlScoutsAreEvil Girl Scouts are Morally Ambiguous]]: Or, at the very least, far too fond of illegal and/or questionably-legal activities to fit in well, which is why Kiki seeks them out at the beginning of ''Shadow City''.
* HandsOffParenting: Ananka's parents.
* HeroicAlbino: Kiki Strike.
* HotBlooded: Luz Lopez.
* MadScientistLaboratory: Dee Dee has one.
* MasterOfDisguise: Betty Bent.
* MineralMacGuffin: The ring Kiki has to steal.
* MysteriousPast: It's hard for Ananka to tell who or what Kiki is because she won't let on.
* {{Nerd}}: Ananka.
* NewTransferStudent: Kiki Strike.
* ObfuscatingStupidity: Oona pretends not to understand English so she can spy on her salon-goers' secrets.
* TheObiWan: Verushka, Kiki's royal bodyguard.
* OnOneCondition: Ananka received an inheritance she's not allowed to spend on anything other than educational fees.
* OrphansPlotTrinket: The inscribed ring.
* PennyAmongDiamonds: Subverted. See ScholarshipStudent below.
* PerfectPoison: Death by chocolate allergy...almost.
* ThePlan: Sidonia. Kiki pulls one over on her.
* {{Ruritania}}: Pokrovia.
* ScholarshipStudent: Subverted. At her school, where the students are split into "scholarship girls" and "wealthy girls", Ananka is the outsider, because one of her relatives left the family money that can ''only'' be spent on education and nothing else. Ananka is neither rich (outside of the education fund) nor a good student, though her low grades are because [[BrilliantButLazy she's bored]].
* SecondaryCharacterTitle: Kiki Strike is the WaifFu-practicing leader of the Irregulars, but protagonist Ananka narrates.
* SixthRanger: Iris.
* TheSnarkKnight: Oona switches on and off with Ananka.
* TalkativeLoon: The captives.
* TruthSerum: {{Inverted|Trope}} in that said chemical actually just makes you seem trustworthy, which makes people ''more inclined'' to give you the truth. It can't ''force'' people to tell the truth.
* TheStoic: Kiki Strike.
* WaifFu: Kiki is the size of a young child and can take out grown men.
* WrenchWench: Luz Lopez.
