To Love Again by Bertrice Small

Beautiful, headstrong, and defiant, Cailin Drusus possesses the pride of her Celtic-born mother, though she has been reared amid her Roman father’s wealth and privilege. When Cailin’s family is destroyed and their farmland seized, she marries Wulf Ironfist, a Saxon of enormous strength and power–a gentle giant who opens the door to a world of heady sensuality. But her happiness is short-lived. For an unknown enemy drugs her as she labors in childbirth–and she awakens to find herself sold to a slave merchant and transported to Byzantium, not knowing what happened to her child. . . .
