Coyote moon - Ralph Hayes

Buffalo hunter O'Brien has made an effort to settle down to a more civilized life in Fort Revenge, in Indian Territory, helping his friend run a stageline there.However, it isn't long before trouble comes at O'Brien from two directions: first in the form of an outlaw gang from Tulsa who want to buy his friend's stagecoach company and won't take no for an answer, and second from a family of killers who are seeking revenge for the death of their kin at his hands. O'Brien must respond to these challenges with his own brand of gunsmoke, while he wrestles with two life decisions: whether or not to return to the trail, and whether to take Sarah Carter, the girl he brought to Fort Revenge, with him when he leaves.
