From back cover: "Morwenna... was just a girl when she first saw handsome, arrogant Maxwell Thurlow, mounted high on the rearing, plunging stallion that had murderously trampled her father. Morwenna... was a young lady when she met Maxwell Thurlow again, in the great manor of Ashridge Hall where she had been adopted and raised. Morwenna... was a woman about to be swept up by a passion for a man she should hate and fear - a passion that inexorably would bear her toward a destiny as dark and dangerous as the nightmare legacy of her unknown past. "
