Harry Potter and the Deathly Hallows by J.K. Rowling

It came around 2pm on Saturday, and by a little after midnight I had it read (even while taking a break to entertain my parents, eat dinner and watch some TV!).

Suffice to say, without saying anything about the story or any spoilers, that the ending was immensely satisfying.

And now that it's over, I'm sad...

Very, very sad. :-(
