Wren Connolly thought she'd left her human side behind when she rebooted five years ago as Wren 178. Then Callum 22 came along and changed everything.

Now that they have finally escaped HARC, Wren and Callum are ready for a peaceful life on the Reboot reservation. But Micah 163, the leader of the reservation, has darker plans in mind—he has been building a Reboot army with plans to kill all humans. Callum wants to stay and stop him. Wren wants nothing more than to leave all the fighting behind.

With Micah on one side, HARC on the other, and Wren and Callum at odds in the middle, there's only one option left.

It's time for Reboots to become rebels.

The sequel to the action-packed Reboot is a can't-miss thrill ride, perfect for fans of James Patterson and Marie Lu. After coming back from death as Reboots and being trained by HARC as soldiers, Wren and Callum have finally escaped north, where they hope to find a life of freedom. But when they arrive at the Reboot reservation, it isn't what they expected. Under the rule of a bloodthirsty leader, Micah, the Reboots are about to wage an all-out war on the humans. Although Wren's instincts are telling her to set off into the wilderness and leave the battle far behind, Callum is unwilling to let his human family be murdered. When Micah commits the ultimate betrayal, the choice is made for them. But Micah has also made a fatal mistake-he's underestimated Wren and Callum. The explosive finale to the Reboot duology is full of riveting action and steamy love scenes as Wren and Callum become rebels against their own kind.
