A Roamer in Time

Miriam Johnson inadvertently escapes to the 12th century with the help of a faulty time-transport device that continually sends her back in time to different countries where she meets historic characters. Her fiancé, Charles Wright, a scientist, sets off in pursuit and is plagued continually by the same time-warp anomalies.
Years later, Miriam Johnson-Wright, married, three months pregnant and feeling neglected, decides to take a peek into her future and falls foul once again of a re-occurring time and space-slip anomaly that sets her down in a number of alternative universes across the ocean in the New World.
