I actually don't know how many pages I've read. I'm on the Kindle Fire reading library digital edition and can't see the page numbers.
I do not know why I had never heard of this book. It popped up in my browsing of the library cloud collection and somehow grabbed my attention.
If you want to know what's behind the aberration of today's, um, situation, this may be the answer. Be warned - the answer is terrifying.
