books for beginning gardeners?

Does anyone have a good book to recommend for a beginning gardener? I got a nice email from Julie who is planning to start a garden and is looking for a good resource.
Hey Kathy, I'm fairly new to gardening and I'm feeling a little confused about where to start learning about it. I plan to start a garden this spring in my parents backyard and I'm trying to educate myself on the basics of this subject as fast as possible. Don't want to totally mess it up :) Could you recommend any sources to study? If you could only use one book on gardening what would that be for you? ps. I'm planning on raising edible foods in my garden
