Somewhere in Time by Richard Matheson
Matheson's classic novel tells the moving, romantic story of a modern man whose love for a woman he has never met draws him back in time to a luxury hotel in San Diego in 1896, where he finds his soul mate in the form of a celebrated actress of the previous century. "Somewhere in Time" won the World Fantasy Award for Best Novel, and the 1979 movie version, starring Christopher Reeve and Jane Seymour, remains a cult classic whose fans continue to hold yearly conventions to this day.
