Reputed throughout the West to be half man, half gun, Rawlin Lassito was a legend in his own time. Books had been written about his vendetta against the Quantrill Raiders who had slaughtered his loved ones and left him for dead in the carnage at Lawrence, Kansas. One by one, he tracked them down and made them pay the ultimate price for their murderous cruelty. He always succeeded because he never cared whether he himself lived or died.

But the trail of the last Raider leads him to San Marco, where he discovers a barbaric slave trade being run under the guise of indentured service. Determined to put an end to the cruelty, Lassito pits himself against the powerful tyrants of the valley and their army of hired guns. This time, the odds stacked against him look insurmountable. But this time Lassito has a secret weapon--he has at last found a reason for living. Will it be enough to pull him through?
