TERRY PRATCHETT!!!
He's written like 30 books, all set on a fantasy-ish world. There are different character lines, with different settings--farm settings, city settings, etc. He tries to capture our world and make it a little easier to understand. With dragons. If you want to give him a try, start with "The Wee Free Men". It's the beginning of the Tiffany Aching storyline, and a great way to be introduced to Discworld.
Also, all of Tamora Pierce. Another fantasy world, loosely based on ancient Europe~love it. I would start with either Beka Cooper ("Terrier" is the first book) or Alanna of Trebond ("The First Adventure" in the Song of the Lioness series)
These series are both easy reads in my opinion, the second series more so. Pratchett actually brings up important social issues in a semi-comedic setting.
