Given my personal obsession with female werewolves, finding out he had not one but two of them, and that Angua was a prominent character, got me invested again after listening to the Thud! audiobook. I also love the Moist books as both of those are a lot of fun. I have a worgen called Captain Angua in World of Warcraft to honour her, though they still don't have a blonde worgen fur colour. I wish I could have experienced her becoming Captain of the Nightwatch in a book instead of reading about it on the wiki. I still don't know what the source of that info is.

Edit: I Shall Wear Midnight mentions it.
