For six thousand years, the rogue planet Chronos has sailed a ghost orbit through the void, its path a masterpiece of mathematics so elegant and impossible it defies the known laws of physics. When Captain Ælfthryth Goldwyn and the crew of the USC Indomitable are sent to investigate this cosmic anomaly, they discover a truth far stranger than any hyper-advanced alien race: Chronos is a lifeboat, populated by the last survivors of a long-dead star system.
The Mnemon are a species adrift in a shared, timeless sorrow, their entire consciousness a living memory of their ancient journey. But when a single act of scientific curiosity—a well-intentioned message from the Indomitable—reveals the fate of their home star, it shatters their fragile peace, plunging the planet’s collective mind into a screaming abyss of psychic terror.
Deep within the chaos of their shared madness, the crew uncovers the horrifying truth. The Mnemon’s ancestors, brilliant but flawed, made a single, infinitesimal error in their calculations. A rounding error at the 257th decimal place has turned their multi-millennia voyage to a safe harbor into an unchangeable collision course with their own sun’s dead heart—a lethal, spinning pulsar.
