Riley Crane woke up fully dressed, a gun under her pillow, and covered in blood. Even more frightening, she didn't remember what happened the night before. In fact, she barely remembered the previous three weeks.

An ex-army officer, now a federal agent assigned to the Special Crimes Unit, Riley was a chameleon -- a clairvoyant who could blend in with her surroundings, be anyone or anything she chose to be. The SCU's expert in the occult, she'd been sent to the beach-front cottage on Opal Island by her enigmatic chief, Noah Bishop, to investigate reports of dangerous and occult activity.

But that was three weeks ago. Now she's awoken to discover that she's got a sexy new man in her life and an unreliable memory, and that the clairvoyant abilities she's always depended on to protect her are MIA. Worse yet, with SCU resources stretched thinner than ever before, Riley is without backup. Alone, she is forced to feel her way through a deadly game of blindman's bluff, where no one around her is quite who or what they seem. And a bizarre murder is on the first jarring reminder of how high the stakes really are.

Bishop wants Riley off the case. So does powerful local DA Ash Prescott. Both her old army buddy Gordon Skinner and Sheriff Jake Ballard believe she can catch a vicious killer. But one of these four men knows exactly what's going on in this coastal community, and that's knowledge Riley desperately needs. For what Riley can't remember is more than enough to cost her her life. This time evil isn't just closer than she thinks -- it's already here.
