What can a hapless reviewer possibly find to say about Anthony's Xanth yarns—here the 21st of that ilk—that hasn't been said before? Astonishing as it may seem, Anthony has found the present puns-and-anything-goes format too restrictive, so he's introduced a miniature planet called Ptero that contains (wait for this) everything in Xanth that is or ever could be! The future sure won't have been what it used to be. So: evidently, nothing much—but stay tuned for next year's adventure (according to reports from Ptero, it'll be about zombies). And, meantime, in the author's afterword, you can catch up on the latest news about Anthony's teeth.
