Dresden Files, the Meredith Gentry faery books (though they are pretty racy and seem to get more so with each new book LOL).
Mists of Avalon - love it - but boy, is it a long read LOL!
I like to re-read Lord of the Rings too every once in a while.
I just got some of the Sookie Stackhouse novels from my mom, and am looking forward to starting them.
I've heard that the Chronicles of Amber is a fantastic series. A friend gave me the books, but I have yet to read them.
