This was a very fast read. Had a hard tme putting it down. I'm not sure how I found this book, I think I just happened to be browising the library and picked it up after browsing the inside jacket, glad I did. Several times it gave me the shivers at how creepy Diedre (The Ex) is. Several portions got sexually explicit that was almost too much, but truly showed the weakeness of David. I truly felt sorry for Mollly (the wife). The ending left me a little flat, which is why I didn't rate it higher. After Diedre's demise, David and Molly seemed to live hppily-ever-after, surely there had to be some difficulty with Molly accepting David's indiscretions. ( )
