The Squire, His Knight, and His Lady, by Gerald Morris, 1999 (Sequel to The Squire's Tale)

Terence, squire par excellence to Sir Gawain of the Round Table, has grown a few years older and developed an eye for the ladies. On a quest in which Sir Gawain seeks a Green Knight who's obligated to chop off Gawain's head (don't ask why, there's a lofty chivalric reason), Terence rescues, or is rescued by, the feisty Lady Eileen of Irish blood and temperament. Monsters, villians, and slightly naughty courtly love abound in this Arthurian coming-of-age romance. Minor stylistic hiccoughs don't interfere with this retelling of "Gawain and the Green Knight's" humor, charm, and good fun. Recommended.
