I just devoured this book, having never read the Discworld Diaries it’s based on. The artwork is fantastic, the details of the various guilds, people, and personalities is top-notch, and the size of the book (fairly large) makes it all the easier to enjoy the contents.
I subtracted on star for some script-like fonts especially at the beginning which were difficult to read. Yes, I should use my reading glasses, but any book large enough to take out a terrier should be easy for me to read without glasses, too.
All in all, an excellent Hogswatch gift, and I look forward to the 2nd volume.
