Never read this guy yet, but one of my favorite pundits has a bunch of his books on last year’s book list, so must say that you are in very good company and must have good taste in literature.
These were on the list:
Guards! Guards!, Terry Pratchett
Interesting Times, Terry Pratchett
Maskerade, Terry Pratchett
Carpe Jugulum, Terry Pratchett
Thief of Time, Terry Pratchett
A Hat Full of Sky, Terry Pratchett
Witches Abroad, Terry Pratchett
Snuff, Terry Pratchett
The Last Hero, Terry Pratchett
