At the moment I'm in the middle of reading Knife of Dreams, the 11th book in the Wheel of Time series. My most favourite of series! The 12th book is due out next year so I had to catch up on all the going's on.
If you haven't heard of the Wheel of Time series, it's very fantasy based, completely in a different world. Amazingly rich in detail and believable in the world that it's based. Many different characters and story lines to follow! If you like fantasy, you'll love this series!
