We too have bounced off Discworld. Pratchett for us is like Gaiman; we must've read at least half a dozen of each, trying to get ourselves into it, and just generally not succeeding. I think with Discworld is that it's just a fantasy subgenre that is generally a hard sell for us!

Also, Annie, this post makes us realize we have zero fictional books about witches on our shelf, haha. It's all nonfiction!
