Yes, VegLover, it is a wonderful book and I, like you, was impressed with all that Julia was. She's an inspiration to the world in so many ways, not just for food-related areas.
Another book you might consider reading is As Always, Julia - The Letters of Julia Child & Avis Devoto.
I just picked it up at my area Sam's Club and can't wait to read it. I know when I begin reading I won't want to put it down.
You might try searching in your area thrift stores and used book stores for the Mastering
books. I've been lucky to find many desirable books at those places for literally a dollar or two. You'll get a bargain and satisfy "your" Julia habit.
