So I just have to say that I absolutely loved this book. It was the perfect amount of suspense. It had great twists and turns. I really didn't want to put this one down because I had to know how it ended. I enjoyed that we had no idea who we could trust at this rest stop. What I really enjoyed was the way the author gave you an answer so quickly that you just knew that wasn't it... I have to admit the book does not disappoint on the new twists and turns. The various layers to this one are just amazing. It really becomes this game of cat and mouse between Darby and the kidnapper. I think it was interesting how the author incorporated this fight for survival in our characters. 

 Darby was a really well written character... she has her flaws but also she has an amazing survival instinct. She quickly adapts to the situations that arise and I enjoyed watching how she problem solved. I have to say the last little bit of the book got super tense and had me on the edge of my seat because I had no idea what was going to happen. It did not unfold anything like I thought it would and I loved that. If you are a fan of the locked in type thrillers I really think this is one that you would enjoy. If you love mind games this one is full of them. It was a really great thriller. It had all the elements. I think it really managed to put the suspense throughout and then save up this huge level of tension for the end.
