描述
An old man wearing a brown robe is found wandering disoriented in the Arizona desert. He is miles from any human habitation and has no memory of how he got to be there, or who he is. The only clue to his identity is the plan of a medieval monastery in his pocket. So begins the mystery of "Timeline", a mystery that will catapult a group of young scientists back to the Middle Ages and into the heart of the Hundred Years' War. Imagine the risks of such a journey. Imagine the impossible.
