I wasn't expecting much when I searched for some kind of writing for this book...
I wasn't disappointed, really.
But then I found this, and I was quite delighted.
Thank you for being awesome and writing this. It really made my day, especially since I finished the book yesterday... So sad, but definitely an amazing read. Thanks again.

So, Mr. B is a book character that is aware he is a book, and the current holder in the story is here for a book burning mission. And he seems to be anticipating it.

From what book is he from?
