Larkin Quinn can't wait until her heart transplant surgery is over so she can awaken to the beautiful and fun life she's desired. But from the moment she opens her eyes, her world is dominated by terrifying nightmares where she is trapped underwater and blocked from reaching the surface. She wakes up each time screaming and drenched in sweat.

She needs to understand what these dreams mean. Are they messages from her heart donor? She fears he is demanding his life back in exchange for hers and wants revenge. Even more frustrating is that no one believes her about the nightmares. Why won't anyone, not even her boyfriend Paul, help her? Larkin has to figure out what is going on with her new heart before it kills her.
