A war is coming.

Kainos is not the planet Exodus Ark colonists thought it would be. It is inhabited by the Volcuri, a once-thriving race that fell victim to the First and now fights for its very survival. With the Ark unable to travel, its people have no choice but to stay and ally themselves with the Volcuri…or risk certain death.

Kent and his team must return to the surface and embark on a new mission: Find a way to defeat the Turned, and stop the First from taking them all prisoner as mind-controlled slaves. Their hope lies in the lost history of the Volcuri’s past, but they only have one clue: The mountain holds the key to survival.
