By most objective measures, this novel deserves only four stars. Maybe even three. The characters have all the depth of soap film. The dialogue is, more often than not, painfully contrived. The plot is comprised of a series of episodes which would strain anyone's suspension of disbelief to the breaking point. And what plot there is is hardly resolved at the end: this tale feels like the first in a series, which it wasn't. But what makes up for all of these faults is the novel's uniqueness, and the unbounded inventiveness of Piers Anthony's unpredictable imagination.
Few would disagree that Anthony's body of work is a mixed bag. Encompassing both fantasy and science fiction, and frequently blending elements of both, Anthony is so prolific that one would only expect his output to be uneven. But I've stuck by him for years, because for every two clunkers there are three gems of various luster. That plus the fact that he's one of the few authors in either genre with a highly developed sense of humor. This novel stands as, perhaps, the ultimate proof in that regard. Who but Piers Anthony could write a science fiction novel about dentistry? Without giving away any spoilers, the beauty of this work is the sheer temerity -- and absurdity -- of casting a frumpy, middle-aged prosthodontist as the protagonist in a tale of galactic self-discovery. Dr. Dillingham's midlife crisis is foisted upon him, as he is abducted by extraterrestrials, sold into indentured servitude, and required to perform dental procedures on a dizzying array of alien orifices. Interstellar oral hygiene is, it turns out, in varying stages of development throughout the galaxy, and Dillingham is thrown into the deep end of this chasm where he must drill and fill for his supper.
If this sounds tedious, all I can say is that I laughed out loud over and over again. And I'm one damn tough room! At times this was brought about by the sheer ridiculousness of Dillingham's adventures. At other times I laughed, despite myself, at Anthony's painful puns. But mostly it was the sense, of which I was acutely aware throughout, that I was reading what must be one of the most unusual and unique science fiction novels ever written. Combining the fantastic with the mundane (one suspects that Anthony was undergoing some rather involved dental procedures at the time) results in a book which can hardly be believed. Not the story, that is, but the fact that Anthony could conceive of it, took the time to write it out, and then convinced someone to publish it! I can't help but admire such a degree of sheer moxie. Anthony has earned several passes on this one!
