Nunslinger 8 - The Brother of Bone Orchard

The year is 1864. Sister Thomas Josephine is on her way from St Louis, Missouri, to Sacramento, California. During the course of her journey, however, she'll find that her faith requires her to take off her wimple and pick up a gun... A terrible accident and a life-changing deed find Sister Thomas Josephine the prisoner of the roughest characters she's yet encountered: a gang of bushwackers and deserters bent on mindless destruction - and getting ahold of the bounty on her head.
But the more time she spends among them the more she comes to understand that they're just boys, cheated of a normal life by the terrible war that is tearing apart the United States. And they're bringing her ever closer to Indian Country... and Abraham C. Muir.
