The war with no name rages on, setting the world on fire. Humanity faces extinction at the hands of the Colony, a race of intelligent ants seeking to overthrow the humans and establish a new order. To achieve this, the ants use their strange technology to transform the surface animals into highly evolved killing machines who rise up and murder their oppressors.
The bobcat Culdesac is among the fiercest warriors that the Colony's experiment has produced. Driven by revenge, and notorious for his ability to hunt humans in the wild, Culdesac is the perfect leader of the Red Sphinx, an elite unit of feline assassins. With the humans in retreat, the Red Sphinx seizes control of the remote village of Milton. But holding the town soon becomes a bitter struggle of wills. While the humans threaten a massive counterattack, the townsfolk protect a dark secret that could tip the balance of the war. For the sadistic Culdesac, violence is the answer to everything. But this time, he'll need more than his claws and his guns, for what he discovers in Milton will upend everything he believes, everything he fought for, and everything he left behind.
Relentless, bloody, and unforgiving, Culdesac is the story of an antihero with no soul to lose, carving a path of destruction that consumes the innocent and the guilty alike.
