Mortimer is the best squire in Sire Emberly's troops, but his liege refuses to recommend him for promotion to knighthood. When Mortimer demands to prove his knight-worthiness, Sir Emberly charges him with an impossible task-to find a wonder. With the help of his faithful mare, a scatterbrained wizard, a frog prince, and a very special vegetable, Mortimer creates his own wonder-the first dragon to ever breathe fire! How much trouble could one fire-breathing creature cause anyway? Mortimer certainly discovers, and learns along the way that being a knight is more than being talented with a sword.
