On a dark night in the winter of 1859, three men entered the home of Dr. Matthew Callahan and shot him dead in front of his pregnant wife. Unfortunately for them, his wife, Li Lian, hails from a long line of women gifted in the dark arts—the witches of the McPherson clan. This diary, written to the child she carries, records her quest from the Nebraska Territory to Louisiana to the frozen shore of Lake Superior, to bring justice to the monsters responsible for shooting her husband in the back. Our long-rifled witch will stop at nothing​—​and risk everything​—​in her showdown with evil.
