I almost didn't finish this book. I had high hopes since it was on the best seller list, but I found myself disappointed. I follow a 50-page rule and after 50 pages, I still wasn't hooked on the book. First of all, I didn't care about the characters. At the beginning, the characterization was flat and I thought the author should have developed them better early on. Second, I found the alternating POV very distracting and made the suspense drag. I kept reading because I still wanted to know what happened. it finally got some momentum for a while, but the ending was a disappointment. it was one of those hum-drum endings that made you wonder why you even bothered to read it. i gave it three stars because of the moments it actually kept my interest and I've read worse.
