Exactly how steamy is this story?
PG-13
Pride and Prejudice and Zombies obviously cranks up the violence and gore to 11, but it also adds a dash of sex. Elizabeth observes, for example, "the way [Mr. Darcy's] trousers cling to those most English parts of him" (59.16). Saucy. Mr. Darcy also makes a bunch of cracks about balls—and, no, we don't mean the place where ladies and gentlemen meet each other to dance.
What any of that has to do with either Pride and Prejudice or zombies, we're not entirely sure, but hey, if you made it through zombies biting through flesh, you're probably good.
