The All Hallow's Eve theme this year - books - wasn't as geeky as some we've had, but I still feel compelled to share the best of the lot. I was not among them, trust me. But in books, you do have COMIC books, so there is that. And of course, genre literature was well represented.
Comics and Manga
Hopefully I'll feel more inspired next year, but at least you got to see some cool costumes from others!
