While horseback riding in the English countryside, sisters, Electra and Emily Crippen find themselves trapped in a tear in time. Thrown back to 1357 England and caught by a local noble, they are in a place that is home but as frightening and unfamiliar as an alien world would be. With no idea how the tear in time came about, the one thing they do know is: they must stay together and stay near to where the event took place in hopes of discovering the way back to their modern life. That certain need to stay together is the first certainty taken from them when one sister is forced to remain in England and one is sent miles away to Wales by royal order.There is one other hope for help the sisters don't know exists. It's Electra's lover, Roger Marchand. A time traveler himself, he never told her of his past. When he realizes what has happened to the sisters, he enlists the help of a scientist friend to help him open the suspected passageway through time. Any effort to save Electra and Emily will likely cost him his life. This was the time Roger came from, a time when his country, France, was at war with England. If he is discovered on English soil while searching for the sisters, he will either be killed or taken prisoner of war. Any risk is worth saving the life of the woman he loves.
