The Joyful Homeschooler by Mary Hood
I just put down this book. I didn't technically finish it since I skipped the chapters on older kids, but I own it, so I can always pick it up again. Great book. Mary is the founder of the relaxed homeschooling idea (basically unschooling from a Christian perspective with none of the radical elements), and reading her things always helps me take a deep breath and chill out about how the kids are doing. She has some great ideas. Favorite quote: "Children are not cattle. They aren't meant to be raised in herds."
