Love Once In Passing — Jo Ann Simon

This is book one in Jo Ann Simon's acclaimed time travel romance from the early 1980s.

Christopher Dunlap, a man of title and privilege in early nineteenth century England, and Jessica Lund, a thoroughly modern woman, suddenly find their lives mysterious entwined in Jessica's late twentieth century world.

Neither understand how Christopher, a man who had been living a happy life nearly two hundred years in the past, is now flesh and blood in Jessica's present.

They soon share a love for each other as deep as it is dangerous, for whatever has brought them together can just as easily tear them apart.
