It took me forever to get through this book, sometimes only managing to get through 1-2 pages a week, but I'm glad I finished it. (The last chapter made it worth it.)
A fairly well-reasoned view of how halakha works, impressively synthesizing a variety of sources in an interesting manner. Halfway through, becomes about religious existentialism, which isn't a bad thing per se. Also, hilarious fake haskamah in the back.
