A complicated murder mystery / police procedural. More twists and surprises than your typical Gerri Hill mystery. There's a lot of angst as the lead characters (both FBI agents) both carry incredible loads of baggage from their pasts. The author very successfully weaved the personal conflicts (arising out of the 2 ladies' pasts, personality clashes and misunderstandings) with the tense and thrilling hunt for the serial killer. The author continually surprises you with new twists after you think you've figured out who the bad guy really is. The sex does not disappoint either.
...My only peeve with this book is that the ladies were so busy trying to stay alive, that they didn't have a chance to do anything to solve the final mystery. The solution was like...handed to them on a silver platter by someone else, like a deux ex machina.
