Seth Grahame-Smith wrote a parody of it which was published in 2009 titled Pride and Prejudice and Zombies. In 2010 he published a prequel titled Dawn of the Dreadfuls.
I never got a chance to read Pride and Prejudice and Zombies when it was first released. Recently, I was at the bookstore and inquired about it and was very excited that they had a copy at a reduced price. I love sales! And as I was doing a tiny squee, the sales girl mentioned the prequel.
Luckily for me I’m still in the middle of a book, so that gives me some time to make a decision. Little zombie girl will just have to wait and find out which book I will read first.
