At first I was frustrated with this book. I just wanted it to get to whatever it was that was at stake. Once it did, it was a really good read. A few parts dragged, and I found myself getting restless again, but then it picked back up, and during the last quarter of the book I couldn't put it down. 
 Definitely a psychological thriller, and one that will keep you guessing until the end. Though the reader will see some things coming, other things they won't, and that's what makes these types of reads fun. Well, I use the word 'fun' loosely. This is a dark read, but anything less wouldn't do it justice. The author has a sharp grasp of the genre, and the reader feels all sorts of emotions. I'm glad this was a book club read for me. We'll have lots to discuss.
