I truly am not sure how to write a review of this book without giving anything away, which is exactly why the summary of this book is so small and tells you to assume nothing. I suggest you take that advice: assume nothing! The characters are unreliable and the story line is believable, which makes for an incredible story! I am amazed at these two writers could put this together. There were times I thought I knew what was going on, then I realized that's exactly what I was supposed to think. However, I was wrong! There were times when I wasn't sure what was happening, but I never felt lost. If you enjoy a book that keeps you feeling unsettled and never want to put it down, then pick this one up!
