Good psychological thriller where author tries to show the inner motivations of each of the main characters
The book has been on the best seller's list for a long time! I generally don't like books that use the "amnesia" construct where the main character doesn't remember certain key things that happened during an event. I think it is a sneaky way to create suspense, and is something that is relatively unlikely to happen. However Hawkins did do a good job with it, and made it believable. I also don't generally like books where there are lots of flashbacks to previous time periods. That always seems to be a cheap way to keep the reader in suspense. When the writer jumps back to explain part of a story, but not all of it, then comes back later to fill in missing information, it seems like a dirty trick on the reader. However, also in this case, I think Hawkins did a good job. There were many time period jumps, but they seemed essential to the story.
The one thing that I caution everyone who might read the book is to pay attention to the chapter headings. I had a problem following the book, warned my wife, and she had exactly the same problem. Each chapter heading is the name of the character about whom the chapter is about. The book starts out with Rachael, and the first chapter is focused completely on her. The next chapter is about Megan, a year earlier. When you first start the book, you think the chapter heading might just be a chapter name -- so I made the mistake of thinking that the chapter was talking about Rachel, and maybe she would meet Megan. It took me several more chapters before I realized I had mixed the two characters up. My wife did the same thing! Look at the chapter heading!
