THERE'S ONLY SO FAR YOU CAN RUN… As a child, Kacey was possessed by the Beast. The Beast made her kill people. A lot of people. After that, Kacey vowed to squash the Beast down, pretend to be 'normal', and to never kill another human--Untamed or Enhanced--again. She managed this then--but now that she's twenty-one years old and living amid the War of Humanity, things are much harder.

When Kacey's Untamed group lay siege to an Enhanced city, a betrayal from within ruins everything. Barely escaping from the tunnels under the city, Kacey and the other Untamed survivors find themselves on the run, with the enemy hot on their trail. But, for once, the Enhanced Ones aren't the Untamed's biggest threat; something else is. Something they do not understand. Something that is causing the very fabric of the universe to unravel. With the dead no longer staying dead, time itself reshuffling, and Kacey's past haunting her, she must learn from her mistakes and fix the future before it can happen. Only that way will the world be stable enough for the Seventh One to fulfil the augury and end the War of Humanity once and for all. But when fixing things means Kacey must work with the Beast, and 'winning' also means losing her most-loved, can turning herself into a monster ever be worth it?
