The Time of the Dark(1982)

Barbara Hambly

A California medieval scholar is pulled into a far-off magical world—and a fight to save mankind—in this novel by a New York Times–bestselling author. As a student of medieval history, Gil Patterson is a woman familiar with dark stories. She knows well the Crusades, the Black Death, and the other horrors of the Middle Ages, but it is another kind of atrocity that has begun to haunt her dreams. She sees forces of evil assaulting a beleaguered kingdom, whose kind people are on the brink of annihilation, and awakes each morning in a cold sweat. Gil dismisses the dreams until a wizard appears in her apartment. He has crossed into her dimension, passing through the fraying fabric of the universe, to ask her help. For mankind to survive he must protect an infant prince, whom he plans to hide in Gil's world. The student of history is about to get much closer to evil than she ever imagined.
