Twisted - Andrea Kane

Twisted is a book about ex-FBI agent Sloane Burbank. She's a consultant now, since she left the FBI after being injured in the line of duty. The novel focuses on a serial kidnapper, rapist, and murderer who abducted one of Sloane's childhood friends. The tension escalates as more women begin to disappear and Sloane's old boyfriend is the FBI agent Sloane finds herself working with. I'm not trying to be vague, but I don't want to spoil this for anyone. It's an excellent book. Highly recommended.
