It was the final glimpse Erin Ramsey would have of her sister: Megan's body, drained of blood, lying lifeless in a New York alley. Tormented by the fact that she hadn't been there when her sister needed her, Erin promises herself that she'll find Megan's killer.
Detective Nicholas Slade tells Erin to go home, back to California. He says he doesn't want her to be the murderer's next victim. But his warning comes too late. Erin is already in danger, in thrall to a man who cloaks himself in shadows and haunts her nightmares.
Erin is desperate to find her sister's murderer-and desperate to avoid becoming his prey-but she feels her own life spinning out of control as the silver-eyed specter from her dreams lures her deeper into his world. Nick may be the only one who can help her, but she's afraid to trust him. Her deep attraction to the secretive detective is tinged with fear. He only works the night shift. He wears sunglasses in the dark. And he may have been the last person to see Megan alive
