Very good general overview to organic growing. He has a very clear writing style. With Jeff Cox you always get the sense that he is not just repeating what somebody else said, but has actual experience with the techniques.
Want to know how to improve your seed germination? How to increase seedling survival rates? Harvest peppers properly? Easily identify everything from aphid damage to Wilt? Get this book and you'll answer all those kinds of questions.
I first found this book in my public library. As I am new to an actual ground garden (as opposed to containers -- even then I am still a novice) and I am becoming even more conscientious of our environment, I decided to give it a try. I ended up having it out on loan for approximately three months and then bought a copy of it from Amazon. I was quite happy with the detail that I found in it. I was especially happy with the section on seeds and seeding (something I seem to have NO luck with so far). Lots of relevant categories and many tips and techniques are given. It covers the basics plus a bunch of added bonuses. Perhaps when I am a more accomplished gardener I won't reach for it as often; but for now, I find it to be very useful. It is a very handy reference book to have on hand.
