Highly recommended for young teens with a taste for historical fiction and a modicum of patience, this sprawling novel tells of a medieval pilgrimage through France to Santiago, Spain. The book takes a cue from Chaucer, telling the stories not only of the protagonists (teenaged fiances who don't get along) but also of the strangers they meet. In doing so, it recreates much of the 13th-century western European world within its pages. Ages 12-14.  (FRN389, $7.00)
