The last Terry Pratchett books I read were The Wee Free Men and A Hat Full of Sky and they were a lot better. 
 Still, a good book. But if you have not read any of TP's books, don't read this first. I remembered the first few books I read were about Morty and the Reaper or something (Discword Series?). They were way before I started Goodreads, and I don't remember their titles. I'd like to reread them. You should probably start on those first if you're new to TP.
