In the 1850s, Jean Rio, a deeply spiritual widow, was moved by the promises of Mormon missionaries and set out from England for Utah. Traveling across the Atlantic by steamer, up the Mississippi by riverboat, and westward by wagon, Rio kept a detailed diary of her extraordinary journey.In Faith and Betrayal, Sally Denton, an award-winning journalist and Rio's great-great-granddaughter, uses the long-lost diary to re-create Rio's experience. While she marvels at the great natural beauty of Utah, Rio's enthusiasm for her new life turns to disillusionment over Mormon polygamy and violence against nonbelievers, as well as the harshness of frontier life. She sets out for California, where she finds a new religion and the freedom she longed for. Unusually intimate and full of vivid detail, this is an absorbing story of a quintessential American pioneer.
