Lol, no! It is not like Twilight in any way! In fact, some of my characters from RPs are in it. They're the main characters! Anyway, it's about twin siblings who try to protect their little sister from an evil organisation.
Fair enough xD well to me you seem good at working stuff out. So why not find some really obscure book covers and try to find out what they're all about?
I bet it was, you don't have to write forever you could have taken breaks or something? xD
