Stop what you are doing, and buy Pillars of the Earth by Ken Follett. It's a fantastic book that was reccomended to me for about a year by at least 10 people. It sat on my book shelf for 6 months (sorry Corynn) but I finally bought the audio book and I'm completely hooked.
There are swords, cathedrals, priests, lords, masons, sex, killing and people starving. And that is just in the first 3 chapters, which I completed yesterday after sitting in my car for 30 minutes after reaching my destination, just so I could hear what was going to happen next.
It's a page turner, people. Get it.
