Once upon a time, there was a library.

It wasn't the oldest library you'd ever seen, or the biggest, or the most well-stocked. In fact, it was hardly much bigger than a small bookstore.
But it had three floors, each one containing a decent amount of genres, and there was a little café next door with a dedicated reading area. It was, altogether, quite cosy.

One day, you decided to visit. I don't know why. Maybe you were going to meet a friend there, or you ordered something at the café and needed to wait for it. Maybe you really did just want to borrow a book.
It doesn't matter. This is your story, not mine.

With nothing else to do but kill time, you walked idly through the shelves of books, looking for nothing in particular. It was extra quiet that day, and nobody else seemed to be in the building.
It didn't bother you, though. Maybe you were used to that feeling. To the silence.

Anyway, that's when you found it.

Tucked in between a vampire romance novel and a detective novel, there was a little red book. You probably would have walked right past it if it weren't for the fact that there was nothing written on the spine.
No name. No author. Nothing at all.

Intrigued, you pulled the book out from its hiding place. Sure enough, there was nothing written on the front cover, and, turning it over, you found no blurb on the back. It wasn't until you flipped it once more that you noticed a sticker that definitely wasn't there before:

You don't know who is lurking here.
Enter at your own risk.
Touch nothing and nothing touches you.

Now, you have a choice. This is your story. What do you want to do next?
