As adventurous as the quests of J.R.R. Tolkien and as contemporary as the zany entertainment of Tom Robbins, "Fool on the Hill" is certain to bring laughs and be remembered for a long time to come. The hero is S.T. George, a young writer-in-residence at Cornell, who is looking for love and dragons to slay. Soon George is caught up in an epic struggle of life and death, good and evil, magic and love. 400 pp.
