Verity (Barforth #1)
Brenda Jagger

Verity knew well why her handsome, womanizing cousin Joel Barforth wed her. She was heiress to a great Yorkshire weaving mill, and her husband lusted for wealth as keenly as he lusted for her.
In return, Joel gave her all a nineteenth-century wife could expect -- a fine home, servants, children, even a growing knowledge of sensual pleasure. Then Verity met a man as different from Joel as day from night -- Crispin Aycliffe, bitter foe of all that her husband represented -- and in his arms she surrendered to the overwhelming, terrifying force of love.
