For years, Detective Brooke Chandler has been deliberately shielded from the supernatural world. But now that the supernaturals know about her, there's no line they won't cross to harness her powers for their own wicked needs. To stay alive, Brooke needs to learn what it means to be a Shadow. Unfortunately, the one person willing to help her may be just as guilty of using her unique skills for his own gain as the people she is trying to escape. Her training comes at a price: helping a fae lord find several dangerous artifacts and shadowing them from his enemies. But the more she uses her abilities, the deeper she becomes embroiled in the cutthroat societies closing in on her. Soon, Brooke finds herself hemmed into a corner, condemned to make an impossible choice that might destroy the human world as she knows it.
