In this breathless story of impossible love, perfection comes at a deadly cost. For Davis Morrow, perfection is a daily reality. Like all Priors, Davis has spent her whole life primed to be smarter, stronger, and more graceful than the lowly Imperfects, or "Imps". A fiercely ambitious ballerina, Davis is only a few weeks away from qualifying for the Olympiads and finally living up to her mother's legacy when she meets Cole, a mysterious boy who leaves her with more questions each time he disappears.
Determined to escape from TOR-N, a corrupt Narxis research center, Davis meets another recovered patient, Mercer, whose sweet smile and quirky sense of humor give her hope in humanity again - and a way out. As they make a perilous journey seeking clues that could lead to a cure, Davis and Mercer's friendship begins to evolve into something more...but she's still struggling to let go of her feelings for Cole, whom she believes is dead.
