Pale Horse Coming — Stephen Hunter

Mississippi, 1951: The last place any sane man wants to visit is Thebes State Penal Farm. Of the few who make the journey there, even fewer return.

But when an old friend disappears inside Thebes, ex-marine and Arkansas State Police Sgt. Earl Swagger takes a personal interest in the case. As he infiltrates the prison, what he experiences defies his wildest nightmares--a savage world where death is the only salvation. As tough as he is, Swagger barely escapes with his life--and his mind--intact. But he's not going to stay away for long. Recruiting six of the hardest, deadliest gunmen ever known, bloody vengeance is soon at hand. Because Eari Swagger is going back to Thebes.
