Civilization: The West and the Rest by Niall Ferguson. I's studying Medieval History at university, so this is a great bridge for me that explains how the last 500 years got us from there to here. Seriously, if you have any interest in history, or why the American Empire is dying and the Chinese, Indian and Brazilian ones are rising (those who forget their past etc.), READ IT!

American Gods by Neil Gaiman was the last book I read. It's pretty good, all about various gods from around the world trying to survive in modern America, and competing with the 'new' gods of technology, media, etc. I intend to hit the bookstore later in the week though, as books are my primary method of delaying my inevitable shooting spree.
To stave off the massacre, may I recommend
Neverwhere by Gaiman? It's really good, and continues his blending of fantasy worlds with the modern one. Or if you have siblings,
Anansi Boys may be more interesting (it's a spiritual successor to
American Gods , set in the same world but with new characters.
