I struggled to understand what was going on in this book at first, however once I picked it up, it was quite the ride. I thought the sheer premise of the book was so interesting. Each day, Aiden wakes up inside other host bodies. He has to separate his feelings and thoughts from theirs, however sometimes their information helps him out in some way. He has to figure out who to trust and why. He, also, has to figure out how to find his way to meet his objective using the different hosts and to be able to communicate with himself as different hosts. This book really takes you on an adventure and keeps you guessing until the very end. I liked that this book was smart and so clever. There was so much going on that impressed me. I will be recommending this book to others and would like to read more from this author.
