The Debt: Scoundrels and Madmen: Cowboy, Soldier Military, Civil War Romance

This is book 2 of The DEBT: a 4-part novella series based on Cowboy, ex-soldier, Matt Stone.

Matt Stone rode into Markleeville one hot dusk, with a wind at his back that promised summer thunder. He was tall and lean, with a narrow, clean-shaven face above the collar of his oilskin duster. His eyes were a hard pale blue, like chips of ice, and his black hair was long like an Apache's and held back with a strip of leather. The coat was open, revealing a buckskin vest and the pair of silver Colts at his hips.
He rode a huge, sleek black horse with a bullet scar showing in white hairs across one flank. Its name was Lucky. That horse had carried him through Gettysburg alive, and then taken him west, where he'd spent three years wandering, trying to get the echoes of battle out of his head.
Matt now has the pay off the debt Lucky has created.
