Pride's Castle — Frank Yerby

A Man Damned. Handsome, fiercely ambitious Pride Dawson came to New York in 1870 to battle his way up in the savage world of high finance. He thirsted for money, power, and all the elegant and willing, hot-blooded women they could buy. He hadn't reckoned on Sharon and Esther. Sharon was shy but sensual, everything Pride had ever desired in a woman, and he knew he'd never stop loving her - not even when Esther came along. Esther was a passionate heiress with a body to match her fabulous fortune, an attractive stepping-stone to success whom he married for more than money and less than love, a sensuous predator who gave him everything he wanted - and made his life a living hell.
