<br/><br/> "Polly Whittacker has two sets of memories. In the first, things are boringly normal; in the second, her life is entangled with the mysterious, complicated cellist Thomas Lynn. One day, the second set of memories overpowers the first, and Polly knows something is very wrong. Someone has been trying to make her forget Tom - whose life, she realizes, is at supernatural risk."--From publisher.
