If this is your first time reading Terry Pratchett, you've just been bitten by one of the most extraordinary legendary beasts of dark humor in our age. Its brilliantly comic venom will flow through your blood and stay with you for life—a bittersweet miracle you'll never wish to be free of.
Your approach to his work is interesting. If you enjoy compelling characters, I recommend delving into Moist von Lipwig. Lol.
