An astonishingly irrelevant review. The style of the book is very good and its very readable. Most North American writers don't even come close to this Canadian (?) woman's fluency and command of English. Secondly it is not repetitive: the author's case is well laid and easily understood (except maybe for the "hard-of-understanding").
I think this reviewer is being mischievous and I hope it is an innocent mistake on his part.
