It's on me that I couldn't rate this book higher; I received and ARC of this book, not realizing at the time it was part 6 of a series. This book was good, I really liked the writing style, the characters (what I was able to learn about them anyway) and the pace of the book were all terrific. It's just the entire time I could tell I was missing something. So take this review with a grain of salt and use it to start the series with Orphan X like I'm going to. I do think based on this book that the whole series is probably great so I'm going to start at the beginning.
