"Here we go 'Adventuring' in Xanth once more, meeting a horde of the familiar characters while running the gauntlet of a multitide of sins. …Xanth remains a land of happy endings, however, and readers can expect the usual amount of enjoyment from this thirty-fourth Xanth tale." --Booklist on Knot Gneiss
