Bitterroot — James Lee Burke

Big Sky country. Billy Bob Holland has come to Montana's Bitterroot Valley to help an old friend in need. But against the rugged, wide-open vistas, it is Billy Bob who is targeted for big trouble. Wyatt Dixon, a prison parolee, believes the former Texas Ranger caused his imprisonment and his sister's death--and he is intent on exacting a deadly revenge. But Billy Bob, tormented by the mistakes of his past, will be a formidable opponent as he, too, sets out to make things all things--right.
