Average story that relies heavily on format. Existential haunted house is not really my genre in the first place. The main things I personally want in a book are characters I care about and/or a strong narrative. I get that experimental writing can work sometimes, but I have a hard time with writing that relies on a gimmick for "meaning." The characters are boring and the narrative itself was quite uninteresting as a horror fan. Maybe I'm missing something since this is on so many horror lists.
