What happens when a magical computing device gets transported from the future, and the marauders (plus Lily) discover interesting stories about them and people they know? And what happens when they attempt to write so-called Fanfiction themselves?

It seems like a dream-come-true when fanfiction-obsessed Chloe gets transported back to the marauder's era. However, she soon finds out that she is actually in the story of her nightmares, with the characters recognizably warped out of shape and cliché after cliché... But that's not the worst part... She's turned into a Mary Sue.
