When Lightning Strikes — Ethan Flagg

Lightning Cal Gentry's reputation as a lethal gunfighter has its downsides: he faces hotheads making their play, and hardcases who want respect and fame. It's hard to remain at the top - and now Cal wants out. But when he guns down Billy Vance in the New Mexico town of Tucumcari, it prompts a manhunt, putting his loved ones in mortal danger. Only with the help of the infamous renegade Apache, Geronimo, can he hope to resolve the issue.
