This is sort of a mosaic novel written by two weird horror authors (that I know personally, hope it's okay to promote my friend's work here) with different styles and outlooks.
It's a fun take on a haunted house, with a mix of Gothic elements and weird fiction vibes.
It's published by Tenebrous Press, currently my favourite small press. They focus on 'New Weird Horror,' valuing new approaches and experimentation within the genre.
