The Carpet People by Terry Pratchett must be one of my favourite books, and is certainly one of the books I've re-read the most (I probably read it at least once per year). Initially written when he was 17, and then re-written when he was 42, it is an entrancing blend of naïveté and a cyical, world-weary outlook.

Set within the hairs of a carpet, it tells the tale of various carpet people, and the upheavals caused in their society by the destructive progress of Fray, an unknown force of great and horrible power.

By setting such major events on such a small scale, Pratchett reminds us of the often ridiculous and irrelevant nature of our struggles.

This is a close personal favourite of mine, and one I would happily recommend.
