You care because you have posters of Theo James on your wall, and you kiss his chiseled cheek goodnight at the end of every single day. Oh wait, we're the only ones who do that? Ahem.

Even if you're not smooching on the actor who plays Four, or taking What Faction Are You? quizzes or getting faction tattoos on your own back, Four is an interesting experiment in both POV shifting and prequel narratives. Haven't you always wanted to know how a certain character got to be the way he was, or what a fantasy world was like before the first line of your favorite book?

Remember how everyone went wild for Twilight told from Edward's perspective? This is like that, except, you know, actually published. The mere fact that it exists gives you no excuse not to grab a copy today.

Do it for Four. But also do it for yourself, because getting the other side of the story is what great literature is all about: you get to borrow someone else's set of eyeballs for a while and see the world (or the apocalyptic dystopian Chicago, at least) from their perspective.
