During his high school graduation party, Caleb receives a letter from his childhood best friend. After reading the letter Caleb decides to forego his plans of traveling to Africa and returns to his hometown in search of his old friend. Once he arrives he finds his dad missing, and also that children and teens have been missing for a while. His childhood best friend, Christina, is locked up at the new Dream Center for sleepwalking and it's his mission to save her from there.
The story is a little slow at first but once it started going I thought it was very good. The sleepwalkers possessed by spirits is one I haven't read before. I like that this book isn't a first of a series. I can't say this book was scary, but then I'm not sure if I have come across a book that has scared me. I do think that possessed sleepwalkers is a freaky thought!
