Two decades following the beginning of The Tuskatawa War, and two years after a second more brutal conflict that was born as a result of that war, Rancid Mahoney is now a gun/ muscle/ anything-for-hire, as long as the money is good enough. Having taken a personal vow of mental and emotional silence against the horrors of his past, Mahoney has successfully simplified his life and takes pride in only one thing: knowing a good deal when he hears one. Until parentless eleven-year-old Billy Hargraven asks of him the simplest of tasks: to be his protector as he traverses the wasteland in search of a doctor who can help his dog. The money is good, and so Mahoney accepts and the three venture out into a burned world filled with the bleakest of uncertainty.

Along the way, they encounter Til Drange, an old companion/sometimes enemy of Mahoney, who warns them of increasing bloodshed in the area that may or may not have a connection to the wars of years ago. The encounter will lead Mahoney into perhaps the bloodiest battle of his life, pitting him against cannibals, malicious creatures, and cultists, but worst of all: his own conscience in regards to Billy's safety, and future.
