The devil wears prada

I am starting to read the book "the devil wears prada" from chapter 1 to chapter 3 which has a 37 pages. When I have tried to find the book for my class, I chose this book in my room, because I already saw the movie but I haven't read the book yet. At that time I have tought that it was going to be easy for me to read, but it is not. Actually, I really hate a reading because I am the slow reader. However, this book was interested me to read better than other book.
The stroy started different from movie and the book, the movie is starting from a woman who is the main character, Ahndreah, she was looking for her job. However, the book is just started from her who already got the job, is performancing which is the personal assitance of the editor, Ms. Miranda Priestly in " Runway" Ahndreah is really stress out of her job, because her boss, Miranda is always giving her a job which cann't do in one time. There are some expression of Ahndreah's feeling bad about her boss, however, Ahndreah cannot quit her job, because she has a big dream and she know the other assistance who was just before her, she already gone for the other job(I cannot find what was the job is -_-I will tell you later^^) so, Ahndreah doesn't give up when she really like to give up, and just go for it. Miranda doesn't like ahndreah's style because she does not care of her make-up or a style in her job , however,she is changing when she knew that. Miranda is continuously ringing Ahndreah's phone day and night, then did not tell any detail about giving her job. Ahndreah is getting exhausted her boss of caprice.
I was hard to read this book because it is showed different between the movie and book. I would like to read again and make clear understanding about this story. See U guys in the class!!!^_^
