When a heart donor is found, Elle awakes from surgery gifted with more than just a new heart—clairaudient messages and spiritual apparitions haunt her until she is convinced that she must be insane. Either that, or her donor is sending a message.
Desperate for answers the medical community can’t provide, Elle’s divination leads her to the family of her donor—a young girl named, Cas. With the help of her best friend, Rob—the guy who’s a testament that her new heart is capable of love, Elle must make sense of the clues Cas is sending. As pieces of Cas’s life and death emerge, Elle will discover that she and Cas share more than just a heart.
