Broken Betrothal: Mail Order Bride (Sweet Western Hearts) by Ruby Hill

This is not really a broken betrothal, just that the groom dies before Nora arrives. Her fiance's son arrives and wants to send her home, but decides she can become the housekeeper. With the arrival of Mr. Arbuckle things start to get interesting and a mystery takes place on how Peter Shaw really died. Good plot, but could have been executed better. Still it worth reading.
