Corey Cobb was born intersex, but because Corey's father and stepmother didn't make a big deal of it, it isn't until Corey's dad dies suddenly and Corey is back with a disapproving mother that making a gender choice becomes an issue.
Corey is now legally old enough to refuse medical intervention--but not old enough to prevent choosing not to choose being considered by Corey's mother to be a psychiatric problem.
While in the youth psych ward, Corey meets Kim, diagnosed as anorexic, and together, the teens discover important, perhaps catastrophic, truths about each one's past.
