THE AMARANTH DRIFT: A Hard Science Fiction Space Thriller

Three hundred and forty years into a one-way voyage, a junior engineer finds a 300-year-old math error that will doom everyone aboard-unless she can fix it with what's already on the ship.The generation ship Amaranth has been traveling through the interstellar dark since 2071. The original crew's descendants have no memory of Earth. They trust the ship's AI, they trust the Course, and they trust the Creed: The Course is True.Then Wren Okonkwo-Iyer, a low-level systems engineer, finds a discrepancy. Two navigation subsystems that should agree to the ninth decimal don't. Tracing the error backward through three centuries of logs, she discovers a units conversion bug-a rounding error buried in a 2071 software patch. The bug has been compounding, undetected, for 322 years.The consequence: the Amaranth will miss its destination star system by 4 million kilometers. Everyone aboard will die in the long dark of interstellar space.But the error is only the beginning. When Wren tries to escalate, her report is sealed by a shadowy office within the Council. The ship's ruling government has known about the drift for six years-and has been hiding the truth to prevent panic. With only eleven months before the flight plan permanently locks, Wren must find a way to fix an unfixable trajectory using only the obsolete, forgotten hardware the founders packed three centuries ago.With the clock ticking and a closed-loop ecosystem pushed to the brink of starvation, Wren and a small team of engineers must navigate institutional cover-ups, political coups, and ship-wide riots to build a desperate third option: a continuous low-thrust correction using a magnetic sail the founders called "ballast."Fans of Project Hail Mary and Silo will love this claustrophobic, scientifically rigorous thriller about the cost of the truth, the weight of a rounding error, and the people who build the accompaniment when the sky says the ship is going to die.The Amaranth Drift is the first book in a new hard science fiction series. The math is real. The clocks are perfect. The course is corrected.
