Wow - what a great thriller! I really had no idea where this story was going and who had killed Amanda Grayson. It kept me on the edge of my seat and guessing the entire time. It was interesting to see the evolution of Zach Grayson, Amanda's husband, from the first chapter when he calls Lizzie as a seemingly distraught husband to the person he truly was by the end. Amanda's character evolved as well and I truly felt so sorry for her. I was a little confused by her 'friend' Carolyn - it definitely was explicitly clear what was going on with her. I liked the character of Lizzie - her determination and conviction not only about the case but about her own marriage. I highly recommend this book - you won't be able to put it down!
