Ysabel, by Guy Gavriel Kay, blends history and fantasy, facts and imagination. Ned Marriner, a 15-year-old from Canada, travels with his father to France. His father, a famous photographer, is there to shoot pictures for his next book. What starts off as a vacation for Ned quickly turns dark and confusing as first he meets an American girl, Kate Wenger, and together they run into a strange and frightening man. Who is this man? Where did he come from? What, if anything is his connection to Ned? Why is Ned experiencing what can best be described as paranormal, supernatural? Ned and Kate get deeper and deeper into an ancient story involving Celts, Romans, and violent French history, which seems to be coming to life around them.
