YOU WILL NOT BE THE LAST. 389339 IS YOUR TURN. Elara pushed back from the desk. Outside the window, the desert stars were cold and patient.
The screen flickered. Then, line by line, 389339 expanded into a sequence of primes, then a crude diagram of a carbon atom, then a string of base pairs. Not DNA as she knew it—a different grammar, a different alphabet of life.
