Better than I was expecting. Very suspenseful. I enjoyed how the main character had to solve the mystery of what she'd been doing for the few days before she'd been kidnapped. I was only disappointed that (view spoiler)[the kidnapper was just a random guy, not somebody she knew or interacted with. (hide spoiler)] 
 I didn't realize until I was about halfway through that Nicci French is actually two authors - Nicci Gerard and Seam French, a married couple. The writing was pretty seamless, and I wonder who did what. I would definitely read more by this duo.
