This is readable and enjoyable in the sense that a Lifetime movie is enjoyable. You wonder why you're sitting there with it, and yet something about it compels you. Probably helps that I was needing a huge distraction in my life at the time.
Although it's likely any real secret society would not allow a book to be written about it, the way this one is pulled off is rather ridiculous. I won't go into specifics here, but while the premise is interesting the way it's pulled off is like, ugh, dare I say it, "chick lit," next to Christian fiction probably my least-favorite genre. Oh, besides westerns. The ending comes off like some kind of John Hughes movies, and my goodness, authors, when you want to model a character after yourself, you can at least give her a different haircut from the one you have in your author photo (I know about this stuff because I have a bad tendency to write many characters who resemble myself as well.) Particularly irritating: the lesbian character who has "a thing for John McCain."
