Luke Yancy apprenticed to a gun-smith when he was just a boy. At fifteen, he fought in the Civil War, and later he became one of the youngest U.S. deputy marshals ever. Now, still in his twenties, Luke is ready to lay down his gun. Then he receives an urgent summons from Lady Katrina Fairchild.

Lady Katrina is ready to lay her railway to Los Rasos. But with the evil Bass Knotter on her trail, she needs the best protection money can buy.

Then Luke is forced into the battle. But his war against Knotter can't stop his feelings for Shasta, who's young, spirited--and Knotter's stepdaughter. Winning Shasta's love could be Luke's toughest fight of all...
