The Maverick by Lori Copeland

When devious spitfire Susanne McCord convinces Papa that Cass Claxton sullied her virtue, the ensuing shotgun wedding provides the escort she wants for her trek to St. Louis. At journey’s end, the hostile travelers part-vowing to annul their paper marriage. Six years later, Susanne desperately seeks refuge for nine orphans. But when her only hope lies in unfriendly hands, she uses a clever strategy to rope a maverick named Claxton.
