On a personal level I have almost too much to say about this and I think I shall reserve that for a different time and possibly a blog. On a literary level, I don't have much to add to reviews that already exist, except to say I think this is now too dated to be of much use. It needs a serious re-write in order to still be relevant.
One of the things this book does with thoroughness that I was not a fan of is detailing personal profiles of big names in the early pro-life movement. I did not find particular value in this, since it's not why I read the book, but for those who really want to dive into "who were these folk and how did they start protesting and eventually bombing abortion clinics?" this might be interesting.
In terms of broader national trends, narratives, and policy, this book is less useful. It starts out in that arena but quickly moves into an almost macro level approach to understanding the lives and psyches of people who propped themselves up as advocates of the unborn. A steady descent towards justification of violence is evident, but the philosophies behind it never fully explored, since such extremists are almost always portrayed as mentally disturbed in some way.
In summation, I did learn a bit, but most from the beginning and end. I was shocked to be reading quotes from George Tiller in the present tense, and finally realized that this was written before he was assassinated, so it really has lost some of its value over the years as violent action against abortionists has somewhat waned, but with the exception of explosive and notable upsurges. Probably only interesting to those who want to explore this on an academic and historic level.
