Alder's Grove

I've been re-reading The Thief of Time, by Terry Pratchett, in part because I just found it in a used book store when cluudle visited Ithaca.

And in this re-read, I discovered that Pratchett had very cleverly explained all of the storyline divergences in Discworld in one tidy plot device.

There are many chronological inconsistencies on the Disc. Creatures and contraptions from a hundred different time periods exist side by side. This is how it's always been... or is it?... -the Discworld Compendium

This is brilliant. The Discworld books were written over such a large span of time, inconsistencies (or things that the writer just didn't like anymore) were bound to sneak in. In one fell swoop, Pratchett wrote a wonderful, readable book, and made any and all consistency errors canon.

Love it!
