Glancing past your computer, and out to the library that you worked at, you noticed a familiar face. Dust was a quiet skeleton who came in semi-regularly, and just minded his business. Instead of walking inside the building without saying a word, like he typically did, he came up to the front desk, seeming fairly hesitant with his upcoming words.
Hello. I was, um, wanting to return this, and check out a couple other books.
Not wasting time on meaningless small talk, Dust placed down the book he wanted to return, sliding it over to you, then followed it with three other books, wanting to read those in his own space. Upon noticing the books, something struck you as odd, Dust appeared as the type to read non fiction, or mystery books, but one book appeared to stand out.
