 This book was really interesting. I liked the way the author incorporated concepts of psychology and physics into the story (even though some of them, like hypnosis, actually weren't accurate it was still cool) and the plot itself was really neat. Besides the plot, the other thing I liked best were Natalie's relationships with her family and Megan. I didn't really buy her relationship with Beau being as all-encompassing and important as it was, but maybe that's just me. Other than that, I really enjoyed this book. The last 50 or so pages blew my mind and the book as a whole will definitely stick with me!
