AP Reading Book

So after an intense long look at the huge list of all the books I had to choose from to read, I eventually chose to go with Atonement by Ian McEwan. I chose this book because I've heard of the movie (I know. I should never base a book off the movie) and it looked really good. I haven't gotten the chance to see the movie yet, so I thought it would be a great idea to read the book first and see what it's about and then watch the movie. That's always the right way to go. Also, I'm a sucker for a good love story. I know the cinemas probably made the whole story about romance, but the book has to have some sort of romance. The movie looks like it would be good, so why not read the book first to get the real story?
