After her mother’s death, Miss Fannie Rousseau—a privileged and self-centered young woman from St. Charles, Missouri—finds a photograph and letters hidden in a locked drawer in her mother’s room. When she sets out on a quest to find her only living relative, she meets Samuel Beck aboard the steamboat both are taking up the Missouri River to Montana. As a young preacher, Beck is on a mission to reach the rejects of society in the remote wilderness—and to atone for the past failures that still haunt him. Fannie and Samuel are opposites in every way … except in how neither one can stop thinking about the other. Will the end of their journey be the end of their relationship—or is it just the beginning?
