As NASA’s Asclepius IV approaches TRAPPIST-1f, pilot Valentina Nelson is tasked with delivering forty-nine sleeping colonists to a new world, until she realizes the colony below has gone eerily silent. With no answers and no margin for error, she must guide the ship in alone, relying on its AI as her only counsel while the crew sleeps on, unaware their fate rests in the hands of a pilot who never wanted this kind of choice. She can divert course and hope another colony will take them in, or continue toward a world that may already be a graveyard—hoping the reason for its silence won’t become theirs.
