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. Amongst the frenzy and the greed of the Colorado silver mines, Sister Thomas Josephine finds that the murders she has been framed with are part of something larger and far more horrifying; the brainchild of a person whose obsession is too familiar to be coincidence. And what is worse, they know her weakness. Finally nearing the end of her epic journey west, Sister Thomas Josephine finds her faith and her strength tested in unimaginable ways. But, with the help of some old friends and a few new, no low-down varmint stands a chance against her!
