This was fantastic. I loved the characters, especially Adam. His family dynamics added alot of tension and frustration to the book, and his and Roberts relationship as brothers reminds me of my own relationship with mine. The worldbuilding was amazing - so unique and well thought out - every chapter adding yet another layer to the Other Side and leaving so many questions. I really enjoyed the idea of the Watchtowers too, and I can't wait to see where Adams story goes. The writing style was easy to follow and flowed so easily. I can't really fault this book.
