From what I saw form the pages Misk sent, it appears that the book automatically rearranged itself, without Lucy doing anything... All she knows is the book (the fact that its enchanted with magic), and the author himself, and used those two knowledge to tell Kaby to open the book to reveal its secrets...

Sooo she technically she has nothing to do with the book. if Kaby opened the book himself without all these Lucy stuff... the magic would still happen.
