Martin Rojas, the bounty hunter known as Tirador, has spent more years than he can remember traveling the stars bringing men to justice wherever someone is willing to pay. Years of training have endued him with the skills of a Firearm, a martial art feared throughout the wild frontier of colonized space. Those skills have brought him a life that is prosperous, lonely, and haunted by past wrongs. But a job on the colony planet of Laredo to bring down what Tirador thinks is a petty criminal will reopen old wounds and force him into a showdown with a man even deadlier than he.
