Raymond E Feist. I suggest starting with Magician: Apprentice/Master. He is my favorite author by far.
Also Devid Edding's Belgariad is pretty good.
Terry Goodkind has a series called the Sword of Truth. I like it more than the Wheel of Time but at the same time I was disappointed by the later books.
I never really liked Raymond E Feist's books. They always felt lacking, like something important was missing.
Devid Edding's Belgariad is a classic but his series get worse and worse after that.
Terry Goodkind's Sword of Truth is alright. If you read the first one and pretend it ends there you will spare yourself from a bunch of filler and a weird elongated ending. I would only finish the series if I had nothing better to read.
Brandon Sanderson's new epic series, that unfortunately only has one book out now, is currently my favorite book ever. Check out the Way of Kings, you will not be disappointed.
Joe Abercrombie and Glen Cook are also very good authors with some awesome books.
If you wanna check out Urban Fantasy then The Dresden Files are without a doubt the best in the genre. There are also around a dozen books out in it.
Finally if you are looking for some laughs then the Discworld books by Terry Prachett are the way to go. It is a satire set in a fantasy realm and the funniest books you will ever read. Maybe start with Going Postal.
