The road to reckoning

Summary: Twelve-year-old Thomas Walker has never left New York City. His father, a traveling salesman hoping to earn money by selling Samuel Colt's recent invention, the "Improved Revolving Gun," takes young Thomas with him on the road. But even the world's first true revolver cannot save them from danger, and what starts as an adventure soon turns into a nightmare. When his father is murdered, Thomas must rely on his own wits, courage, and determination, as well as a wooden replica of the Colt revolver, to protect himself. Luckily, an encounter with a surly ex-ranger, Henry Stands, leads to an improbable partnership, and the two set out in perilous pursuit of vengeance--that is, if they can escape the thieves who lurk around each trail, river, and road.
