Darcy Jones doesn't remember anything before the day she was abandoned as a child outside a Chicago firehouse. So she isn't surprised that she doesn't recognize Conn, the new boy at her high school, even though he seems to know her—or at least know something about her.
What does surprise her is how quickly she comes to trust Conn, and that he makes her feel both desire and desired in a way she hadn't thought possible. But his interest in her is confusing. It doesn't line up with the way he first looked at her.
As if she was his enemy.
When Conn betrays Darcy and she is arrested, she realizes that she can't rely on anything—not Conn, not herself, and not even the laws of nature. Because this world isn't the only one. Darcy belongs in an alternate world where the Great Chicago Fire never happened, and deadly creatures called Shades terrorize the human population.
Darcy needs some answers.
And she hates that the person most able to help her get them is Conn.
