I've been knitting for some time, and done mittens, sweaters, hats, lace, cables, fair isle, etc., but never socks. I could never make sense of the directions for doing a heel, so I just didn't do them. This book has an illustration and explanation that not only makes sense, it makes it simple! I'm about to turn the heel on my first pair of socks, and plan to make some lace ones after these. The patterns range from simple to very complex, and include baby bootees and kids' socks, as well as all sorts and styles of adult socks. Fantastic!
