Trapped in Twilight, Help!

Edythe Elizabeth Swann, a peculiar name for an extraordinary girl with an awful story. It was a simple day in your average ninth grade class, it was the day after winter break and the day after she finished reading Twilight. Nothing big, right?
Wrong. Let's just say that Edythe is more than happy to have a photographic memory. It comes in handy when you mess up a whole population's future. Although, the more she thinks about it, the more she realizes that it could be for the better. Maybe.
Join Edythe on her roller coaster life as she goes through the ups and downs of learning that it may or may not be a very good thing to change a minuscule detail to an over-all saga.
