Revelation Day. The Fall, #6

Years have passed since the cascade of events known as The Fall began. Kell McDonald has struggled through endless fights and privations, suffered war and kidnappings, and even lost a leg. His role in the rise of Chimera, the organism responsible for reanimating the dead and altering the living, is now public knowledge. Through it all, Kell struggled to complete his work and find a cure. When that moment finally came, the horrible consequences of his discovery were driven home.
Everyone wanted it, none more than the mysterious colony of survivors in the budding state of New America. Spearheaded by Rebound, a project designed to restart civilization after a nuclear war, New America will stop at nothing to get their hands on Kell and his work. Tired of hiding, he and the people of Haven are going to end the threat once and for all. To do it, they'll have to fight through the hungry dead while using every shred of cleverness at their disposal to stop their human enemies.
With luck, it might even be enough.
