Seventeen-year-old Eva is a chosen one. Chosen to live, while others meet a swift and painful death from an incurable virus so lethal, a person is dead within days of symptoms emerging. In the POD system, a series of underground habitats built by the government, she waits with the other chosen for the deadly virus to claim those above.

Rafe is a normal teenager from Boulder, Colorado. He plays soccer. He's won skiing prizes. He likes to write. And, oh yeah, he's gay. He's been out since 8th grade, and he isn't teased, and he goes to other high schools and talks about tolerance and stuff. And while that's important, all Rafe really wants is to just be a regular guy. Not that GAY guy. To have it be a part of who he is, but not the headline, every single time.

Sixteen-year-old Canny Mochrie's vacation takes a turn when she stumbles upon a mysterious and enchanting valley, occupied almost entirely by children who can perform a special type of magic that tells things how to be stronger and better than they already are.
