Bunch quitter

the long version

"He'd fought to stay alive for six months ... and when he returned to his home town, Chance Ragan had just one thing in mind -- to prove he was as good a cowhand as he'd ever been -- and that was the best. But he found he'd run smack into the roughest deal he'd ever tackled. Before he was done, he'd fought his way with hands and teeth and feet through three of the town's toughest bullies -- and even then he still had to prove he was as fast with a gun as he'd always been."
