Ever since Rosa's nerve disease rendered her quadriplegic, she's depended on her handsome, confident older brother to be her rock and her mirror. But when a doctor from Boston chooses her to be a candidate for an experimental brain transplant, she and her family move from London in search of a miracle. Sylvia—a girl from a small town in Massachusetts—is brain dead, and her parents have agreed to donate her body to give Rosa a new life. But when Rosa wakes from surgery, she can't help but wonder, with increasing obsession, who Sylvia was and what her life was like. Her fascination with her new body and her desire to understand Sylvia prompt a road trip based on self-discovery... and a surprising new romance. But will Rosa be able to solve the dilemma of her identity?
