I checked out a copy through the library... it is really great, I tell all my prego friends to read it (most are more "mainstream people" - but a couple have said they want no drugs even thought they are having a hospital birth. I haven't gotten any feedback from them whether they have read it or not though...).
Anyway, great great book, especially if you are like me - fairly non-confrontational, so when people challenged the birth I wanted I could quote the book, or re-read parts to get me all fired up again about what I wanted!
