Entertaining chick-lit! I have seen some of the film, too, but that wasn't too impressive. So I'd stick with the book!
This is the story of Andrea Sachs, a college graduate who lands a job as personal assisstant to Miranda Priestly, editor-in-chief of fashion bible Runway. Andrea has no interest at all in fashion, and takes the job as a stepping stone to serious journalism. However, Miranda soon proves to be the boss-from-hell. Taking on this job drains Andrea's soul as she loses contact with the outside world, casting aside her family, friends and boyfriend in order to meet Miranda's outrageous demands.
