Book Four of the best-selling Train Through Time series, a historical time travel romance series set in and around Seattle, Spokane, Wenatchee and Montana in the early 1900s. Nathan Carpenter has lost the woman he loves...on a train...to another time. He has lost everything, even himself as he cannot find a way to return to his own time...to 1906. Amanda Cartwright can't remember the stranger who accosts her on a train one fateful night, though he says they were engaged to be married...in another time...over 100 years ago. Time and the fates seem to conspire to keep Nathan and Amanda apart. Is their love strong enough to find each other in time?
