When fifteen-year-old Ana finds out there was a mistake with her test, her whole world crumbles. Now, joining with Pure-boy Jasper is her only hope of salvation.
But when Jasper disappears, Ana sets off on his trail, determined to solve the mystery of his abduction. In doing so she uncovers some devastating truths, but she also learns to love as she has never loved before.
A compelling debut from a powerful new voice in YA fiction.
