Recently realization:
I don't understand why people include a summary of the book in a book review? If I am reading your review I either a) have read the book and therefore already know what it is about or b) am thinking about reading the book in which case I can read the blurb at the top of the page (or on the book jacket). I don't need you to tell me what the book is about, just tell me if it was executed well.
