New York Times bestselling author Kay Hooper saves the best for last in the almost unbearably intense conclusion to her spellbinding Fear Trilogy, which already has over one million copies of the first two books in print.

Agent Riley Crane of the FBI's Special Crimes Unit is used to dealing with bizarre situations and violent death, but when she wakes up alone, head pounding and covered in blood – human blood – she knows she's entered a new kind of nightmare. The trouble is, that's all she knows. With the last two weeks of her life wiped from her memory, Riley's in the middle of an undercover operation where friend and foe look terrifyingly alike, and where the murderer could be someone close to her. Perhaps someone she loves. Perhaps even…herself.
