Traveling on a shuttle bus after a transatlantic flight as a newly-minted tour guide, Kate wakes up from a nap to find she is hurling alone through space.
She is then plunged into the dangerous past of 1818 England.
Alone in a strange world that shimmers with danger, she is aided by her one contact, Michael Sorville, Earl of Lanquest, after their initial contentious meeting in which she explains that she is not from his age.
Lanquest helps her adjust to the present she must live in while he works with her to get her back to her time. As the days go by Lanquest falls in love with Kate and is less and less eager to see her go, just as she is not eager to leave the one man who has invaded her heart and soul as no man ever had.
