Picture this: You’re in a bookstore, and you see the cover: the Marion Chronicles. Marion? Sci-fi? You pick up the book, turn it over and read the blurb to decide whether or not it’s worth the effort. Except we’re not in a bookstore, and there’s no back cover. Therefore I don’t have to follow any of the rules about how long it has to be. This is the why you should read the book blurb.
