Hoo boy, where to start. First and foremost, you have A Song of Fire and Ice series by George R.R. Martin, probably one of my favorite fantasy series' thus far, although the wait for the next book is killing me. =(
Then of course, there's The Wheel of Time by Robert Jordan, another incredible series that has me waiting and waiting for the last book.
The Shannara series by Terry Brooks is a great one, pretty short trilogys that you could easily breeze through.
Margaret Weis and Tracy Hickman are the ones that got me into fantasy novels with the Dragonlance trilogys, also short and you could read in a few days or hours depending on how much and fast you read.
Right now I'm diving into The Runelords by David Farland, so far it's pretty exciting, about to get into a huge war. His take on magic is pretty interesting, take qualitys from one person and endow another pretty much ruining the givers life.
I'm sure there's some others I'm forgetting, but those are the main ones of importance, if you haven't read them, go to a book store and stock up. Now.
