More Than a Mistress — Joan Mary Hart

Lisa had been young and in love-- and totally naive--when irresistible Scott Bradshaw proposed. Otherwise, she might have realized that a hardheaded, self-made millionaire would devote more vigor to amassing his fortune than to building a marriage. Divorce had been the only answer.
