Wildwood by Katharine Kincaid

During the glory days of the British Raj, Englishwoman Emma Whitefield sets out to claim her inheritance—a plantation in the wilds of India. Only one man can help her search for her elusive dream: Alexander Kingston, a man as exotic and mysterious as India itself. In the proper world of the Raj, any sort of liaison with a rogue of Mr. Kingston's reputation would be shocking and forbidden. Yet he is the only one who seems even vaguely familiar with the whereabouts of her land. Unbeknownst to Emma, her inheritance lies at the very heart of 'Sikander's' own hidden empire...and he will never allow this bold, heedless spinster to seize and destroy all that he holds most dear.
