Lindy West in a review of George R.R. Martin's A Song of Ice and Fire:
Basically—here is the dark, mewling shame-baby that's been calcifying for years in my brain-womb (medical term)—I will read anything with a fucking fictional map in the front.
Ohhhhhh, how I crave a fictional map! Oz, Middle Earth, Narnia, Neverland, Fantastica, Tortall, the Wizarding World of Harry Potter, the one with the talking war-bears where everyone gets to have a magic otter that is their best friend... uhhh... Dinotopia... ummmmm... you know, all the other ones. All the main ones. I love that shit. So imagine my delight upon discovering that not only does each volume in George R. R. Martin's A Song of Ice and Fire series have a fictional map in the front, IT HAS A FUCKING FICTIONAL MAP IN THE BACK, TOO. That's two fictional maps. Two. (Plus sometimes a third supplementary fictional map that I really can't get into right now because I need both hands for typing, if you know what I mean [MASTURBATION JOKE].)
All hail fictional maps.
