Despite all efforts to the contrary, there is at least one error in the first edition of the hard cover book. (It was fixed prior to release for the Kindle edition, but too late for printed copies.)
In the very first chapter, on page 4, I accidentally reversed the attributions of the Harris and Hitchens quotations. This reversal carries through the first chapter. As a result, on pages 27-30, each instance of “Hitchens” should say “Harris.”
Any further errors will be shared here, as well.
