Yes, I think that just about sums up my own concerns about the book as well Rhiannon. You read through it thinking, "mmm... that's interesting." but know you're going to have to check out what the author is saying elsewhere.
Perhaps the value of books like this is that they do get you thinking and so personally I wouldn't dismiss it completely.
