“Five years ago, Wren Connolly was shot three times in the chest. After 178 minutes she came back as a Reboot: stronger, faster, able to heal, and less emotional. The longer Reboots are dead, the less human they are when they return. Wren 178 is the deadliest Reboot in the Republic of Texas. Now seventeen years old, she serves as a soldier for HARC (Human Advancement and Repopulation Corporation).

Wren’s favorite part of the job is training new Reboots, but her latest newbie is the worst she’s ever seen. As a 22, Callum Reyes is practically human. His reflexes are too slow, he’s always asking questions, and his ever-present smile is freaking her out. Yet there’s something about him she can’t ignore. When Callum refuses to follow an order, Wren is given one last chance to get him in line—or she’ll have to eliminate him. Wren has never disobeyed before and knows if she does, she’ll be eliminated, too. But she has also never felt as alive as she does around Callum.

The perfect soldier is done taking orders.”

I really liked this book.  I loved the interaction between Wren and Callum and I loved the role reversal in this book.  Wren is the strong one and Callum is the one who needs to be saved.  In this world, sometimes death isn’t the end.  There is a virus called KDH that has killed a lot of people, but it has also caused some of those people to come back to life.  They call it rebooting.  The only problem with this is that they come back very different and humans are afraid of them.  They put them in facilities and turn them into soldiers.  They are basically prisoners and have no life that the facility doesn’t allow them.  Wren has been in a HARC facility for five years, ever since she was killed at 12 years of age and rebooted.  She has the least human characteristics of all the reboots at the facility.  She was dead for 178 minutes before she rebooted.   A new group of reboots has been brought into the facility for training and among them is Callum.  He was only dead for 22 minutes and is very human like and full of life.  He is not at all cut out to be a reboot.  Wren decides to train him and gets caught up in his charm.  The other reboots think that she doesn’t feel anything, but she is just better at hiding it.  Callum breaks down all of her walls and it comes to the point where she just can’t lose him, even if the leaders of the HARC facility want him gone.

I would recommend this book to others and I will definitely read the sequel.  I would give it four out of five stars.
