Fatal Justice — David Robbins

Years ago Marshal Asher Thrall shot killer Ben Sharkey in the leg to save a fellow lawman. Since then, every crooked step has reminded Sharkey of the man who put a bullet in him. And he's set to repay the favor in spades.

When the Gunsmoke clears, Asher is all too eager to ride after his nemesis. But time is against him. Because while Sharkey shot him three times, the doctor removed only two slugs. The third is still in the marshal's chest -- and with every breath, every heartbeat, it is moving closer to ending his life.

Asher knows he's a walking dead man. Before he dies, he's going to make sure Sharkey is one step ahead of him.
