Having seen the show, (showcasing friends of ours), I was stimulated to look back at the books, and see if I'd missed any other books in the series, and it turns out that my school's library hadn't purchased a couple. I'll be getting to one later this year, apparently written in the 80s, and easy to come by on Amazon.com, but I had missed the second book of the saga, written in 1958! Beware of the Mouse was out-of-print, and available on Amazon for sale, but at approximately $300!!! After I finished the two really large books that had slowed my reading down so much lately, I tried searching the book in the local library systems. The Los Angeles County Library System showed that they had a couple of copies, and I ordered it to be delivered locally...and it arrived in just two days!
It's set in the 1400s, and dealt with the citizens response to advancing technologies in the world around their land of Grand Fenwick. I hate to spoiler this; let it be written that this chronicle of the land deals with how a technologically inferior people can still bloody the nose of a larger and more savvy land, and make it not worth their time and effort to invade. It's a good story, and probably one that certain politicians should ponder well.
I enjoyed it very much; the whole series are quick reads, funny, and intelligent. They're worth hunting down, even if they aren't in print.
