Im reading The Name of the Rose by Umberto Eco... Josh sawyer basically making pentiment based off his love of this book made me finally pick it up. monk mystery with lots of natural philosophy and theological discourse and a labyrinth.

re:Celeste

house of leaves was a crazy read.. i got the rec of a book called piranesi that has similar elements. Thomas Ligottis stuff also feels sorta related vibe wise if you like shorter stories.
