UNTIL WHEN
Humanity did not conquer the stars.
It optimized them.
In the year 2400, interstellar travel is routine, cryosleep is reliable, and uncertainty is treated as a flaw to be eliminated. Swen Adler is a pilot trained to exist where time fractures—awake while centuries pass, trusted to intervene only if perfection fails.
When a flawless colonial mission to Ross 128 b begins to feel too perfect, Swen discovers that humanity may not be expanding into the universe—but simplifying itself for it.
Until When is a quiet, cerebral science fiction novel about optimization, control, and the cost of removing error from the future. There are no heroes to save the world, no wars to win—only a single question that grows harder to ignore:
How long can humanity remain human... until when?
