I picked up this book after seeing the funny trailer that was released a little while ago. I thin this will be one of those movie improves on the book movies, which do happen, if rarely. Mainly because they got Tina Fey to play the sister.
It's not a terrible book and it does have some good moments. Wasn't a long read. I actually got through the whole book while visiting family, and I never have a lot of free time when that happens.
