Almost Heaven by Judith McNaught
Elizabeth Cameron, the Countess of Havenhurst, possesses a rare gentleness and fierce courage to match her exquisite beauty. But her reputation is shattered when she is discovered in the arms of Ian Thornton, a notorious gambler and social outcast. A dangerously handsome man of secret wealth and mysterious lineage, Ian's interest in Elizabeth may not be all that it seems. His voyage to her heart is fraught with intrigue, scandal, and a venomous revenge. As a twisting path of secrets takes them from London's drawing rooms to the awe-inspiring Scottish Highlands, Elizabeth must learn the truth: is Ian merely a ruthless fortune hunter at heart?
