Sabre, a hardened survivalist and former slave, converts to Christianity after she dies and goes to hell, only for Jesus to pull her out. He sends her southward, a suicide mission in this harsh, fraying future full of zombies, gangs, vampires, slavers, and man-hunting cannibals. Along the way, Sabre meets Johnathan "Booth" Fayers, and his daughter, Blair Fayers, on their way to Dallas. Together they learn about love, faith, one another, forgiveness, and trusting in God.
