There's a thoughtful, well-articulated response to this book sitting somewhere in my brain, but for now I'll just say that I really enjoyed the scholarship and evenhandedness of this book; how it never shied away from the topic, but never devolved into a jeremiad (as it undoubtedly would have in the hands of may other authors).
Topically, the book was fascinating, but I can't imagine it has a particularly broad appeal - either you hear what it's about and immediately want to read ir, or you're uninterested in the topic and the book won't change your mind.
One note - I was very pleased to find that, despite being a profoundly academic book, this work was mostly free of jargon. It's much harder to write an academic text in a coherent manner than it is to just fling a post-modern word salad at the page and see what sticks, so my hat is off to Rav Finkelman (though, you know, not in public) for managing to write so clearly.
