This is the best researched book I've ever read.
The amount of time that went into researching this book astounds me. William and his research team spent over a decade’s worth of full-time work, almost two years of which was spent fact-checking. This is sort of like a blockbuster book. I've also found the ideas presented incredibly engaging and interesting, and even where I ultimately disagree with parts of the author's arguments, I think that there should be no doubt that this book represents an extremely compelling and invigorating point of view which should be receiving much more debate and discussion than it has so far.
