Cursed journey of the peculiar Bentleys

"The Bentley family is peculiar indeed. Twins Eliza and Leander and their parents always seem to know more, dream more, and do more than the other families in town. When they decide to head west toward promise of the unknown, every day becomes a new adventure. But when one wild night causes Eliza to lose her most precious possession, it seems to curse the entire Oregon Trail. Could a thirteen-year-old girl be the downfall of the pioneers?"--Provided by publisher.
