I read a book when I was in elementary school that I haven’t been able to find the name to. I imagine it was a kids novel but I’m not exactly sure but the main character was some sort of kid. I think it may have been a boy but I remember specifically that the protagonist was friends with a ghost. I also remember a scene where he goes outside and sees the friend from a hospital window and it’s like a big moment because I think he didn’t know the friend was a ghost. The vibes were like ‘Noah Barleywater Runs Away’ by John Boyne but I’m pretty certain it’s not that book.
