Query: Good, but not the best

This book is well worth reading, although it isn't the best book in the Xanth series. Like "A Spell for Chameleon" and "The Source of Magic", the plot zips from one action-filled adventure to the next, and there's plenty of light-hearted humor. However, some of the jokes and puns start to feel a little bit flat, and the 'surprise ending' really isn't much of a surprise.
