Wow, I am so glad I read this book. I have always recommended Lucifer's Hammer to people looking for a good, relatively realistic post-apocalyptic novel. Alas, Babylon is just as good, if not better. I had never heard of this book or the author until I started researching the best apocalypse novels (I had an itch that only they could scratch). This novel is widely considered to be the best of its kind. I agree.
