At All Hazards (Hearts Afire, Bk 1)

When Eliza and Billy Foreman are called on a mission to settle the San Juan country of southeastern Utah Territory, Eliza doesn't know what to do. A native of London, England, she considers herself a lady, much too fine to be pioneering in a howling wilderness inhabited by outlaws, Texicans, and two separate tribes of warlike Indians. To make matters worse, her later-in-life marriage to Billy has proven a terrible embarrassment, and it now seems doomed to failure.
