I am reading two books right now...
Less for fun but more because of current political reasons:
Bush at War by Bob Woodward. Cannot say much about it yet because I just bought it. So far has some interesting details about the backgrounds of Sept 11th 2001.
The other book is
A Game of Thrones by George R.R. Martin. It is actually the first book of the fantasy saga
A Song of Ice and Fire. From many fantasy fans I've heard that this is the best fantasy book out there. Supposedly even beats Lord of the Rings. Again, I cannot say much about it yet, because I couldn't get much father than page 100.... the price I must pay for working too long these days

What I read so far looks promising; and I like Martin's style... very clear and precise.
