Starred Review Riley has a secret. The androgynous 16-year-old is gender fluid. Some days the teen wakes up feeling like a boy, others like a girl. Riley dresses gender neutral, though that isn't enough to forestall belief at school that Riley is either homosexual or transgender. Not surprisingly, bullying results, most of it sparked by a football player and his toadies. At the suggestion of Riley's therapist, the teen begins writing as "Alix" in a pseudonymous blog that provides a place for candid commentary on life as gender fluid. Surprisingly, the blog goes viral and Riley's true identity is discovered by an enemy who may out Riley. This could have a disastrous impact on Riley's emotional life as well as the teen's father's campaign for reelection to Congress. Garvin's novel is one of the first YA books to deal with the complex issue of gender fluidity. To emphasize the dynamic nature of this situation, the author avoids references to Riley's birth-assigned gender. This means eschewing personal pronouns, a device some readers will find frustrating but nevertheless underscores readers' instincts to put individuals into a box. The novel has its share of histrionics ley's typical reaction to situations is to have a panic attack, a device that gets old t for the most part, Riley's emotional life and personal growth shed welcome light on a hitherto obscure subject.
