I'm not trying to be a bummer, but you might as well leave your book at home. Here's why: there's just not going to be enough space in your beach bag for something that will not get used. You might think you'll sneak in a few pages while your husband takes your child for a swim, but you won't. You'll secretly be playing lifeguard from your beach blanket, all while delighting at the sight of it.
