The power grid failed. The fences fell. Humanity is no longer at the top of the food chain.
Eighteen months after a catastrophic blackout unleashed genetically engineered prehistoric predators across North America, former wildlife officer Gideon Rusk and his teenage daughter Tess navigate a brutal new ecosystem. They find temporary refuge in the walled settlement of Harrow, but Gideon immediately recognizes the fatal flaw in their concrete fortress. A massive migration is tearing through their valley.
The fleeing herds are driven by a tyrant king of unimaginable size. This towering carnivore reshapes the continent with every ground shaking footstep.
As a ruthless coup fractures Harrow from within and intelligent pack hunters systematically probe the perimeter defenses, Gideon must lead a desperate evacuation into the untamed wild. Standing behind walls is a guaranteed death sentence. To outlast the changing environment, humanity must stop fighting the prehistoric food chain and learn to adapt.
