I don't quite know where to start with this book. I've read several Dan Rhodes books and liked them but this is a very disappointing read.
The whole book seems to be a hatchet job on Richard Dawkins who Dan Rhodes clearly intensely dislikes. Not a funny hatchet job either. He creates such a grotesque caricature of Dawkins, so out of line with the reality, that the "jokes" just fall flat. You repeatedly think "well, he just wouldn't do that though, would he?". I have read to the end, where there's a revelation (which I won't spoil), but that just makes the book all the weaker in my opinion because it prevents Rhodes having to realistically (and humously) engage with his subject.
I think Dan Rhodes is criticizing what he *wishes* Richard Dawkins was, not what he actually *is*. This is why he creates such a ridiculous straw man and appends such a lame get-out-of-jail-free clause at the end of the book as a way of dodging any serious criticism.
As for Richard Dawkins, I think he can confidently remain silent and hold off the lawyers. On the evidence of this book, Dan Rhodes seems intent on committing literary suicide anyway.
