Texas Payback (A SLATE CREED FUGITIVE WESTERN)

The Civil War was hell for Captain Clete Slater, a forgotten hero of the Confederacy, and the Texas Reconstruction's even worse. His Texas home-town is overrun with carpetbaggers and bluecoats. He's hunted by the law for a crime he didn't commit. He rides south to Mexico with a new name, Slate Creed, to hide his real identity.
Riding across the Rio Grande, Creed expects to find frontier justice for the real culprits - a murderous gang of bandits who killed his brother. Instead he finds another country torn apart by its own civil war. And Creed must choose which battle he wants to fight: Mexico's or his own.
