What's a better mash up than Pride and Prejudice and Zombies? How about Jane Austin's Fight Club! (Video link with sound.) If they want donations to make a feature film, sign me up! (Provided they have nude oil/jello wrestling, of course.)
I've been reading "Abraham Lincoln: Vampire Hunter" not a bad twist, dude mostly gets away with it (I have some quibbles on style) - but don't let Muad read it, he'd have to attack someone with a knife, lol.
