From the back cover:

"Women are dying - killed with ritualistic precision. Does a journal revealing salacious secrets of some of New York's most powerful men contain clues to the killer's identity?

Butterfield Institute sex therapist Dr Morgan Snow is instantly intrigued by her complex new client, Cleo Thane. When Cleo, a high-class prostitute, asks Morgan to read her unpublished tell-all diaries about her exclusive clientele, Morgan realises it's explosive.

Then Cleo disappears.

Detective Noah Jordain is trying to stay one step ahead of a serial killer who has been targeting prostitutes - could Cleo have become his latest victim? He approaches Morgan for a glimpse into her patient's life, but Morgan refuses to breach confidentiality. Instead, she begins her own investigation. Certain that the answers lie within Cleo's manuscript, Morgan delves into the private confessions of a woman paid to act out sexual fantasies. Too late she realises she's ventured into dangerous - even deadly - territory."
