With pluck, guile, and magic, foundling Wren rescues her friend, the princess Tess. Always dreaming of theatrics and heroics instead of weeding and washing, Wren made a poor showing as an orphan drudge. Thus when her fellow-orphan, Tess, turns out to be a princess in disguise and invites Wren to come live with her, Wren leaps at the opportunity. Alas--the wicked wizard, king Andreus carries out his plot of revenge against Tess's father by kidnapping her; Wren--accompanied by the Magic School's best apprentice, Tyron, and its worst, Prince Connor--sets out to rescue her. On the way, Wren's friends are captured and Wren is turned into a dog; but with the help of the Princess' powerful friends, plus her own growing magical abilities, the wicked King is finally overcome. Smith's story, begun when he was 18, carries the traces of youthful romance and adventure. The characters are well drawn; the story, if a trifle convoluted, moves swiftly. There are unmistakable signs of a sequel, which will be welcome. A superior dog-and-sorcery novel.
