A Reservation in Hell - William Alan Webb - Bog

Surviving isn't living, and living isn't surviving, and in ruined Kansas City neither is guaranteed. When Jace and Pard run into the vicious Warlord of Kansas City, King KaMo, blood and death quickly follow. As cunning as he is deadly, KaMo's position is nearly unassailable, but the duo must find a way to save the lives of their friends and families from a man with no enemies strong enough to hurt him. That is, until he catches the attention of the 7th US Cavalry Brigade (Reinforced), and has to deal with members of Task Force Zombie.
