A library, lots of sweet, and overweight. All mixed in with Rainbow Dash. Things that no one ever thought would mix. So, one action story loving mare gets into Binge reading a book with more chapters than there are pages. It's something that would bring worry to anyone's friends.

The librarian, who had an unknown visitor for so long, appears. And then proceeds to send Rainbow Dash into the very book she so loved, where her hero once lived and died, unbeknownst to her. A massive spoiler to her, but a massive deal to the world that is that very book. And she takes up in his footsteps.
