Dragon of the Prairie by Sarah J. Stone

Life is hard on the prairie. It is even harder when you are a London socialite on the run from killers. This is something Margaret Thorn knows all too well. When her flight from harm leads her to pursue life as a mail order bride, she fears the worst will become of her either at the hands of bad men or a life she never wanted. Meeting her husband, Angus McCord, for the first time does little to quell those fears. His rough, weather beaten good looks let her know that it will be a hard life she is expected to lead, but what choice does she have? Little does she know that her secret is nothing compared to the one he keeps, as she soon finds herself being saved by a dragon. Sometimes, the life you didn’t plan is exactly the one you were meant to live.
