Over a decade has passed since the ant queen began her apocalyptic war with the humans. In the aftermath, she leaves behind a strange legacy: a race of uplifted animals now trying to make their way in the world they destroyed. While the conflict has left deep scars, it also has allowed both sides to demonstrate feats of courage and compassion that were never possible before. And now the survivors have a fleeting chance to build a lasting peace. But the holy city of Hosanna --- where animals and humans form a joint government --- finds itself surrounded by wolves who are determined to retake the land. A powerful matriarch has united the rival wolf packs, and the looming violence soon pulls in those who sought to escape.

In the aftermath of the War With No Name, the Colony has been defeated, its queen lies dead, and the world left behind will never be the same. In her madness, the queen used a strange technology to uplift the surface animals, turning dogs and cats, bats and bears, pigs and wolves into intelligent, highly evolved creatures who rise up and kill their oppressors. And now, after years of bloodshed, these sentient beasts must learn to live alongside their sworn enemies --- humans. Far removed from this newly emerging civilization, a housecat turned war hero named Mort(e) lives a quiet life with the love he thought he had lost, a dog named Sheba. But before long, the chaos that they escaped comes crashing in around them.

The bobcat Culdesac is among the fiercest warriors fighting for the Colony. 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. As the humans threaten a massive counterattack, the townsfolk protect a dark secret that could tip the balance of the war. For the brutal 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.

Former housecat turned war hero, Mort(e) is famous for taking on the most dangerous missions and fighting the dreaded human bio-weapon EMSAH. But the true motivation behind his recklessness is his ongoing search for a pre-transformation friend --- a dog named Sheba. When he receives a mysterious message from the dwindling human resistance claiming Sheba is alive, he begins a journey that will take him from the remaining human strongholds to the heart of the Colony, where he will discover the source of EMSAH and the ultimate fate of all of earth's creatures.
