First on my list has to be Harry Potter. I've read The Hunger Games but meh, wouldn't reread it. I'm currently reading the Fablehaven series and I really like it. I'm going to start the 5th book when I finish Half Blood Prince.
I have Game of Thrones but haven't read it yet. I have Lord of the Rings but haven't read it. Ever. That I can recall anyways. *gasp* I know. lol
I'm in the middle of reading Anne Rice's vampire series. I read the Mayfair witches on paper and loved them!
Oh! and Michael Scott's the Secrets of the Immortal Nicholas Flammel series which I really loved. I enjoyed his mix of real life characters and events interwoven with his own story.
