Did the third and final book in the trilogy come to a satisfying end? Yes, yes it did. 
 The shift in loyalties and personalities in this book was exciting and confusing at the same time. I was questioning motives the entire time. We saw a new side of Zach.... HE HAS REAL FEELINGS!!!!!! I was surprised that this is the direction his character developed in, but it made the story more interesting. 
 Characters: 
 Zach: I liked the personality change. One that wasn't too drastic to be unbelievable, but more of a development from the emerging warmth I saw in him already. I loved how he came clean to a lot of people about his situation and life. 
 Tanya: I was so suspicious of her from the start, when we found her with Howard. She seemed pretty shady- turns out she was!!! (view spoiler)[Besides that she was a part of the program (hide spoiler)] She was interesting and had a great mix of mystery and emotion in her character. I liked the way she interacted with the boys and that her motives were true in the end. 
 Howard: ah Howard. Continually getting captured and having to be saved by Zach and Tanya, whilst giving witty remarks and making bad jokes. Anyone else feel a stiles stilinski vibe??? Besides that, I liked the group dynamic with Howard and his smart comments were funny. 
 Plot: 
 I think this book was epic. The twists and turns, the mystery and confusion, the character development all kept me on my toes. The changing of locations was interesting too and Zadoff did well in explaining where we were and what was happening. 
 Writing: same as always, clean interesting and easy to understand :) 
 All up a fantastic series that I'm glad I read. I don't know if there will be another in the series, if there is I'm going to read it :) Good job Zadoff, you did really well :)
