In that case, how the heck could you have written a book summary without mentioning that? I don’t mean any disrespect to you personally, but this review seems like a bunch of cherry-picked points (whatever appealed to you) which might well completely side-step what the authors had in mind! We can consider this an exhortation of your views on your blog (which is okay to discuss), but it’s really unfair to the book/authors to pretend that it’s an accurate summary of their work that we’re discussing.
