Its an interesting start. However i think it could benefits from a bit more fleshing out. Like showing her enter the library for the first time and a bit of the time she spent there. Other than that its pretty good.
My plans for the story are that, the world is just too big for any 1 person to get a full grip on its entirety, Questions aren't going answered because the Narrator is just another reader, and you are being read the story by them, they aren't a reliable narrator, cause they can only know so much about the story at once, this story in the future will have alot to do with the world between worlds, that borders fiction and reality and the omniscience of the reader and Author and how deep the depths of their knowledge can go.
