This book had so many involved characters I was really left guessing who killed Amanda and even when I thought I had it figured out, I was completely wrong. I really liked how you got a glimpse into each of their lives by the way the author wrote the book from the different character perspectives but it wasn't so detailed that it was too much and boring. Zach's character was really a piece of work from the beginning, you're wondering why would this guy just call Lizzie out of the blue when they were merely acquaintances in college. There's always more to the story of course. I found myself hoping as the story went along that Zach would get what was coming. I'm glad that storyline played out so well. As a hopeless romantic I also found myself rooting for Sam and Lizzie. It was overall a fantastic read I couldn't/didn't want to put down. I look forward to reading more books from this author.
