Go there and click "About a feast for Crows". Read.
Then click Sample and read the sample chapter.
Then go and read the first 3 parts in preperation for getting your greasy mits on the next part of this epic story.
Please for Pete's sake, read A Song of Ice and Fire (the name of the series), it really is very very good and I am terribly excited about reading more into this fabulously realised and brutal world Martin has created.
Ready. Steady. GO!
EDIT: Seriously though, Gibby should star in the movie of these books, they were made for him.
