Wait....Did You Say Zombies?

"And when she was nervous-- as she was nearly all the time since the first outbreak of the strange plague in her youth-- she sought solace in the comfort of the traditions which now seemed mere trifles to others.  The business of Mr. Bennet's life was to keep his daughters alive.  The business of Mrs. Bennet's was to get them married" (8)

"She was a woman of mean understanding, little information, and uncertain temper.  When she was discontented she fancied herself nervous.  the business of her life was to get her daughters married; its solace was visiting and news" (45)

How does the author of Pride and Prejudice and Zombies take what Austen created, and turn it into a world full of action while introducing more sarcasm into the novel?

           I would like to first start off by saying I just couldn't resist.  This is suppose to be a literary interpretation, but I find myself vastly in love with Pride and Prejudice and Zombies and went "awwww" when I couldn't click to the next page.  But what made it so very toxic?  Yes, the action and the random encounter of zombies did help, but I also believe that the style of the novel helps by taking a more sarcastic tone.  By doing this, the book actually revealed more to me than the original Pride and Prejudice, which is amazing to me.  For instance, in the quotes above, I stopped and thought to myself, "wait...they're seriously making fun of Mrs. Bennet here, that didn't happen in the other book."  But when I took a look into the passage, I found that they indeed made fun of Mrs. Bennet, but in a more subtle way, something I was never able to catch.  This happened several times just within the few pages given.  The favoritism given by Mr. Bennet is enhanced, the ball is torn apart by zombies, where Darcy first gets a real glimpse into Lizzy, something that only happens in Pride and Prejudice when she first talks to him.  I am truly astounded that the author was able to take this very difficult novel and understand it enough to zoom onto particular events, some of which I was unable to comprehend, or were too drowned out by the long run on lines that seemed to never end.  I am immediately picking up this book and reading it, but funny thing is, not just for the zombies and action, even though that is a very big part of it, but because I actually think this book might help me understand Pride and Prejudice just a little bit more.
