The Invisible Wings (The Invisible Library Fanfic)

This is a FanFic I'm writing off of the book, The Invisible Library:

Alister meets Silver when they were both younger and that's when Alister lost his wings, Silver tried to prevent Alberich from taking his wings and that is why in The Invisible Library he knows that they must keep the book away from Alberich. But how much will Irene, Kai, and Vale find out about this mysterious Alister? Is he really a Librarian? Or is he just lying....

(uh, sorry I such at summaries!)
