I've been reading Terry Pratchett's Discworld series, and I find he's a great author. He creates an entire world, and is able to put the world in the reader's head through footnotes explaining everything he alludes to. And, of course, he's friggin hilaroious. In my opinion, his best book is Theif of Time.
What do you guys think of Terry Pratchett?

My favourite Terry Pratchett book is any of the ones with Commander Vimes in it. In fact nearly all his books are my fav.

R A Salvatore is another great author. Google search him.
