Guy Gavriel Kay
Guy Gavriel Kay (born November 7, 1954) is a Canadian author of fantasy fiction. Many of his novels are set in fictional realms that resemble real places during real historical periods, such as Constantinople during the reign of Justinian I or Spain during the time of El Cid. Those works are published and marketed as historical fantasy, though the author himself has expressed a preference to shy away from genre categorization when possible. (Wikipedia)
