I have mixed feelings about this book. The idea for this book was very original and obviously well thought out as well as being captivating. There were a couple times in this book I felt like things were moving too fast. Don't get me wrong I hate slow moving books as much as the next guy, but it seemed like things were moving so fast it made some of the more complicated concepts confusing. Other than that I really liked this book. It was filled with mystery, romance, and adventure, making for an exciting and captivating book.
