I don't remember much about this book, which I know doesn't help. I remember reading it in class in year 6 back in about 2016-17. From what I can remember, it's about this kid who I think either transfers to, or joins this weird school for some reason. The only vivid detail I can remember is that when he goes to sign his name to join, he had to write it with a feather quill or some sort of nib pen which he had to prick his finger with and write his name in blood.

That's about it when it comes to what I can remember. I have this feeling that the book cover had the school building on it and the name was written in a goosebumps-esque font. However this is merely a feeling, don't quote me on it.

Any help would be very much appreciated
