" The Library of Fictional Volumes.”

Ahead of us, silhouetted against a brilliant orange sunset, was a tall, rectangular stone building with banks and banks of windows.

“Fictional volumes?” echoed Cole. “You mean novels and short stories? But why would they keep the ship’s logbooks there? Aren’t logbooks nonfiction?”

Andre said, “It’s not a fiction library. It’s a fictional library of fictional books. Some are fictional fiction and some are fictional nonfiction.”

“Isn’t all fiction fictional? Isn’t that what the word means?” Cole objected. “And what’s fictional nonfiction? That doesn’t mean anything.”

Dr. Rust explained, “The Spectral Library is where we keep books that only exist in books. Like . . . What’s a good example, someone?”

“The Mad Trist of Sir Launcelot Canning,” suggested Andre.

“Exactly! The Mad Trist of Sir Launcelot Canning is a work of fiction—it’s a medieval romance. But it only exists in the Poe story ‘The Fall of the House of Usher.’ The narrator reads The Mad Trist to his crazy friend. You can’t find it in any ordinary library, but we have a copy here in our library of fictional books. It’s fictional fiction. "
