内容简介：
Greg and his sister, Heather, medical doctor, have their lives changed when a mysterious woman arrives with a letter from their father, who they thought was dead. Far from being, he explains in the letter that he is very much alive, but is living in the past; so far in the past as to be in the Dark Ages, with King Arthur. Adventures follow. Heather is kidnapped by the evil Morganna, Arthur's archenemy. Follow Greg and his father on the journey of several lifetimes, with battles, death and heartache. When an evil far greater than Morganna is unleashed, friends and enemies join together. Can they overcome their differences, and that of the enemy? What help will Marlin be? And what about the wolf? This novel is set in present day and 500 AD.
