Recently I've finished re-reading Shelter for the Spirit: How to Make Your Home a Haven in a Hectic World. I saw the author speak in person at a Speaking of Women's Health conference several years ago. Nice, nurturing simple living read (with additional bonus of a short appendix with sections about homebirth and homeschooling :). It inspired me to change my Facebook profile quote to: "A simplified home feels friendlier. A simplified life seems easier. And remarkable joy comes from simple things--like having work to do that matters, and having people to love who matter a lot."
I also re-read Mother's Intention: How Belief Shapes Birth. Lots of good stuff in this one, though it does get repetitive after a while. She has a particular way with analogies that is just great--all kinds of good examples. She has a very straightforward, matter-of-fact style. I wish I could manage to be so honest/upfront with some of my childbirth education clients about "buying the hospital ticket and taking the hospital ride."
I read The Pocket Doula as well. It has lots of good pictures, no new information for me. Very conventional approach to standard interventions--doesn't question them at all.
I also read Fearless Fourteen and Finger-Lickin' Fifteen. Nothing like a little "dessert" every once in a while! :)
I think there may have been some others also, but I'm not keeping them in a to-blog-about pile anymore so I lose track!
