Very basic creepy haunted house type story but really well written. This would work so well as a tv show actually. It was very creepy but also sad. The last chapter felt a bit out of place, suddenly there's a wider world involved in what is up to then a really insular story. It would have been nicer if the ghosts could have been more effective, I was really rooting for them.

There actually being an organisation dealing with people like Norah and Jonah felt a bit meh, it didn't have any forshadowing or backstory

That said, the character sketches for each chapter are really good, and knowing what was happening just made the tension mount a whole lot. Creepy af, it's a good book.
