The grandson of a Scottish clan laird, Duncan MacTavish is shocked to learn that his other grandfather was an English marquis whose title and London estate he is now required to take on. Worse still, he is engaged to a stranger who has mocked him in public. But his bride-to-be, Ophelia, has been guiding a lovely and witty, if dreadfully inexperienced, country girl named Sabrina through the latter's all-important first coming-out season. The enchanting Sabrina enthralls Duncan much more than his own intended does, and she shares his passionate feelings as well. But duty and circumstance - plus a scandal in Sabrina's family past - have made it impossible for her and the dashing highlander to be together . . . unless true love can somehow, miraculously, find a way.
