First impressions of this book - from the cover art and the blurb on the back cover - are not good. The cover art by Jim Gurney is similar to that of Josh Kirby on Pratchett's covers, only not as good, and the blurb makes it sound like just a bad comedy of one-dimensional automatons. So it's a good thing that the book was free froma fellow Bookmooch and user I didn't see it before requesting it.
Right from the start, there are at least two Real Characters, plus a couple who are, if a bit stereotyped, are at least three dimensional. Incidental characters who pop up later are also reasonably well-drawn. The plot is, of course, absurd. We knew that from the cover art, and it doesn't make a whole lot of sense, but that doesn't really matter. The comedy is primarily in observing the characters, and I recommend it as a bit of light reading. Don't expect actual quality, but it is at least a quick and entertaining read.
