The books are all well maintained and free of dust. Whoever owns these books takes great care of them, as not even the shelves they're sitting on are dirty. Despite that, they show no signs of wear and tear, as though they were bought from the store, placed directly on the shelf, and never read. Weirdly, none of the sides of the books have titles written on them; as you take the first one down to have a look through it, it catches on something. A little force, and the book tilts forward; an audible kachunk rings through the room, muffled by the walls.

The book falls free after the noise, revealing a strange mechanism behind it, built into the wall behind the shelf and fed through a hole in the back of said shelf; a lever of some kind? In any case, the book itself isn't all that interesting. It goes into incredible detail about the aerodynamics of butterfly wings and various experiments and extrapolations regarding their ability to cause hurricanes. Roll perception.
