 Jory Dean spent 2 years in a coma. Two years not knowing the status of his brothers. Two years of nothing. Now he has the chance to escape, and nothing will keep him from completing his goal to repay his brothers -- to disable the chips threatening their lives -- even the gorgeous, brilliant woman tasked with disabling his own chip. 
 Piper Oliver isn't sure who to trust. The traitor everyone warns her she shouldn't trust, or the father she didn't know until she was in hot water? When push comes to shove, Piper is an intelligent, quick thinking, computer hacker. While working to reconnect with Jory's defective chip, she begins to question everything and everyone. 
 There was so much action in this last book of the series. Threats from the Commander and Dr. Madison and PROTECT means Jory and his brothers have more to consider at each move than ever before. And for the first time, they had more than the four of them to consider. 
 I loved the additional characters added in this book, especially Chance and his brothers, and my heart broke to watch their reactions to the things going on around them. 
 All four Dean brothers and their women together makes for a great mix of alpha male and strong women. For men who never knew a true family growing up, they have done a fantastic job of building an extended family in adulthood. While the action scenes were graphic and detailed, it was the scenes with the family that really keep me coming back to this series. 
 The dynamic of the women together always makes me smile as their men attempt to maneuver situations and then have to step back and let their women help. Laney and Piper especially play huge roles in this book, and watching their men try to protect them while giving them room to work was great fun. 
 This was a great end to this series. While the original Dean brothers' stories seem to be complete, there are enough threads left hanging at the end that it wouldn't surprise me to hear an announcement about a Sin Brothers spin-off, and I would jump in with both feet if that were the case. 
 I was gifted a copy in exchange for an honest review.
