William W. Johnstone presents the adventures of Smoke's long-lost brother Luke, who was reported killed during the Civil War. The war is over and Luke is very much alive, his soul forged by the violence he witnessed on the battlefields. His job is now tracking down the worst outlaws--by any means necessary.

Luke Jensen brings a body to Rio Rojo. After all, it's his job, and he's going to get paid. But before he can collect the bounty for killing a killer, two notorious criminals hit the Rio Rojo bank. Now Luke can't get paid unless he catches professional bandit Gunner Kelly and his Apache sidekick Dog Eater. Unfortunately, a would-be man hunter is after the money-toting outlaws, too, and young Hobie McCullough is mostly a menace to himself. With a green kid to protect, renegade Mexican soldiers, and a beautiful runaway bride crossing Luke's trail, the blood hunt takes one deadly detour after another. . .until Luke ends up smack dab in a nest-of-vipers outlaw hideout. There, he discovers the true identity of Gunner Kelly, what kind of ungodly terror he has planned, and just how dangerous being a bounty hunter can be...
