You type "Contact Carl Sagan Epub" into the search bar—not fully awake, maybe a typo, maybe a wish. The first result is a familiar Gutenberg-style page: Contact by Carl Sagan, EPUB, free download. You click.

You look up. The air shimmers. A man in a corduroy jacket, with a beard of twilight and eyes full of spiral galaxies, sits on the edge of your cluttered desk. He smells of woodsmoke and ozone.

He nods toward the window. Outside, the stars have shifted. Constellations you don’t recognize wheel overhead.

Your heart thuds. A voice—not from speakers, but from the air around your desk—speaks softly, with that unmistakable, gentle, cosmic lilt.

“The EPUB,” he says, tapping your screen. “Every copy contains a quantum-entangled appendix. When someone truly wishes to contact me—not just read about me, but reach —the entanglement collapses. And here I am. Or rather, a recursive echo. The real Carl is long gone. But the conversation? The conversation can still happen.”

What do you ask the ghost of Carl Sagan, summoned by an EPUB?
