''Fearless'' is a young adult novel series by Francine Pascal. The story follows Gaia Moore, a teenager who was born with the inability to feel fear, as her terrorist uncle "Loki" messes up her life.

In 2003, the series was loosely adapted into a [[Series/{{Fearless}} TV show]] starring Creator/RachaelLeighCook in which Gaia is an FBI agent. Only one episode was filmed; it never aired.

A short follow-up book series in which Gaia joins the FBI, ''Fearless FBI'', was published in 2005.
!!Provides examples of:
* ActionGirl: Gaia
* AlphaBitch: Heather. She eventually stops being this and even jumps to Gaia's defense when the FOH start mocking her in the final book.
* AmnesiacDissonance: [[spoiler:Oliver/Loki]] following his ConvenientComa.
* ArtisticLicenseBiology: The supposed explanation for Gaia's condition is that she was born without the gene that makes people experience fear, but there is no such thing (fear is much more complicated than a single gene). In additional material at the end of the last book, Pascal admits to having made up the explanation.
* BackFromTheDead: [[spoiler:Sam]], but the implication is that reports of his death were exaggerated and that he was actually held prisoner by Loki's {{Mooks}}.
* BlessedWithSuck: Gaia is fond of pointing out that humans feel fear for a ''reason''.
** Also, her supreme fighting skills come with a serious drawback: She can't hold back when fighting, so even a simple brawl causes her to overexert herself, which results in her passing out once the fight is over.
* BrainWashed: We learn [[spoiler:Tatiana]] was once a nice person, before getting BrainWashed... then it's [[AbortedArc never mentioned again]].
* CainAndAbel: Loki and Tom
** To the point where, when Gaia demands Tom's location from Loki, he sarcastically asks her "Am I my brother's keeper?"
* CardboardPrison: Loki spends, like, one chapter in a supposed "maximum security" prison before escaping.
** It helped that he had people working for him inside the prison.
* CloningBlues: [[spoiler:Josh]]
* CuckooNest
* CursedWithAwesome: Loki's point of view on Gaia's fearlessness. His attempts to recreate it don't go so well though.
* FauxYay: Gaia does this with Mary Moss to mess with a police officer who has [[MistakenForGay mistaken them for lesbians.]] [[note]]Mary is helping Gaia walk after one of her [[PowerStrainBlackout Power Strain Blackouts]].[[/note]]
* GeniusDitz: Zolov, Gaia's chess partner from the early books, suffered from Alzheimer's Disease to the point where he couldn't even remember that Gaia's name wasn't "Cindy." He also royally schooled her at chess every time they played, which is no small feat, considering that Gaia is the equivalent of an internationally ranked Grand Master.
* GirlPosse: Whom Gaia dubs the "Friends of Heather", in reference to the AlphaBitch. Said AlphaBitch pulls a HeelFaceTurn later on, while the rest of them continue to act like little harpies.
* AGodAmI: One villain actually calls himself "God". He's quite delusional, and is viewed with nothing but contempt by the other villains.,
** Loki as well, after the Norse god of trickery.
* IJustWantToBeNormal: Gaia
* ItsNotYouItsMyEnemies: A major hindrance to all of Gaia's relationships.
* LoveAtFirstSight
* ManipulativeBastard: Loki
* OutOfTheInferno: Referenced metaphorically in "Blood": After Gaia is stopped from almost killing Skizz, Tom Moore watches her as she attends [[spoiler: Mary's]] funeral. When she gives her tear-filled speech on her friend's behalf, Tom reflects that Gaia has "been through the fire and emerged tempered, not charred."
* ParentalAbandonment: Gaia's uncle killed her mother and her father is off working for the CIA.
* PoorCommunicationKills: If any of the characters ever actually explained anything to each other clearly and truthfully, 90% of the tragedy and {{Wangst}} wouldn't happen.
* PowerStrainBlackout: Gaia has this problem when fighting.
* ProfessorGuineaPig: [[spoiler:Loki with the Phobosan 2.0]].
* PsychoSerum: Loki's various "Phobosan" drugs.
* RedemptionEqualsDeath: [[spoiler:Ella]].
* TheMole: Anyone Gaia ever trusts. ''Ever''. Including but by no means limited to [[spoiler:Oliver]], [[spoiler:Ella]], [[spoiler:George]], [[spoiler:Josh]], [[spoiler:Natasha]], [[spoiler:Tatiana]], and [[spoiler:Yuri]]. ''And those are just the ones I can think of off the top of my head.''
** Liz Rodke breaks the pattern. She was genuinely unaware that her family was up to anything evil. According to her brother Skyler, they kept her out of the loop because she can't keep a secret.
* SequelSeries: ''Fearless: FBI''
* SpotTheImposter: Between Tom and Loki
* SuspiciouslyAproposMusic: The band ''Fearless''.
* TeenGenius: Due to her ActionGirl skills, this part of Gaia's character is often forgotten. She has a higher-than-average IQ, speaks multiple languages, and is an expert in decryption.
* TruthInTelevision: The scientific journal ''Current Biology'' recently reported on the curious case of [[http://www.livescience.com/health/woman-has-no-fear-ptsd-101216.html a woman who does not experience the emotion of fear]].
** Francine Pascal once said that she got the idea for the series from a similar article that she read.
* VillainousBreakdown: [[spoiler:Ella]] early on, [[spoiler:Loki]] near the end.
* WickedStepmother: Ella, in the first major story arc (well, technically wicked foster mother, but her foster father is a friend of her biological father's, and Ella is his new wife, so close enough).
