I don't read fantasy books but I am just going to throw a name out there.
D.J. Machale - he is the creator of Are you Afraid of the Dark. Since then he has become and author, mostly books for teens I am pretty sure but from what he told me, anyone can enjoy his books. I suggest some of you guys that like to read fantasy check him out. Let me know if any of you already have. Thanks.
R. Scott Bakker - His Prince of Nothing series is absolutely amazing. It's really heavy on world building and reads like a philosophy text at times, but those are things I really like.
Patrick Rothfuss - Despite major plot-holes, I really did enjoy The Name of the Wind, and I have Wise Man's Fear on my bookshelf, ready to be read.
Anne Lyle - She's a new author, with only one book out right now, but I'm finding myself completely lost in The Alchemist of Souls. I can't wait for her next book to come out.
George R.R. Martin - of course. He's local, so he's usually at all the conventions here and is really nice and encouraging to other writers. Plus, his writing is great. I'm working my way through the A Song of Ice and Fire series slowly but surely. I've got signed copies. <3
