The Bartered Bride — Lois Stewart

The widowed Lady Diana had only one passion: her ancestral estate at Abbottsleigh. Her brief, disastrous marriage had been arranged to save her family from financial ruin, and she vowed she would never again wed for money. Then she attended a masked ball in London...and was soundly kissed by a handsome stranger. He made her knees weak, her blood race, and her reason flee...

The son of a British banker and a half-caste Calcutta woman, Jared Amberly had returned to England from India to seek revenge against the society that had scorned him. Having made his fortune, he proceeded to purchase the gambling debts of Lady Diana's wayward brother. But his generosity came at a cost: the lovely Diana as his wife. Yet, beginning with a stolen kiss, his best-laid plans went awry. Amberly had thought to buy a bride. Now it was he who was at the lady's mercy--ready to pay any price...for love.
