Sin killer

"It is 1830, and the Berrybender family, rich, aristocratic, English, and fiercely out of place, is on its way up the Missouri River to see the American West as it begins to open up." "Accompanied by a large and varied collection of retainers, Lord and Lady Berrybender have abandoned their palatial home in England to explore the frontier and to broaden the horizons of their children, who include Tasmin, a budding young woman of grit, beauty, and determination, her vivacious and difficult sister, and her brother."--BOOK JACKET.
