It's a LOT of information, this book. It's a large number of suppositions carried to seemingly-outlandish-but-actually-completely-logical conclusions, each meticulously researched.
My mind is still kind of reeling...will try to more thoroughly review at a later date.
I will say that he could have used a punctuation expert, especially in the first part, but truly throughout the book. Honestly, though, that's a bit of a nitpick. It's a strong effort and truly made me think. I won't say it changed my perspective because I agree with the majority of the ideas, but it added some depth to it.
