When Lucy walks out of a frozen forest, wearing only a silk dress and sandals, she isn't sure how she got there, or when, or why. But when she sees Colin, she is sure that she is here for him. Colin has captivated half the girls at Saint Osanna's, but no one has ever held his fascination the way Lucy does. With each day their lives intertwine more deeply, and even as Lucy begins to remember the details of her life - and her death - neither of them is willing to give up what they have, no matter how impossible it seems. But when they discover a point where their realities overlap, and Colin becomes more obsessed with testing the limits, Lucy starts to wonder whether there are some lines that should not be crossed.
