Brenda Joyce 
Captive 

"The haunting song of a distant era calls the beautiful graduate student to her subject, the enigmatic Captain Blackwell.Across the centuries, she is drawn by an inexplicable passion into a realm of mystery and danger–to be imprisioned in an opulent world of harem intrigue and sensuous slavery.And now Blackwell is with her–patriot, privateer, heroic commander of the U.S. merchantman the Pearl–the dream, the desire made achingly real. Imperiled captives of fate, they are united by a power far greater than time–and by a passion that could destroy them both . . . or forever change the course of history.
