03:40. A January sky over the North Atlantic. Two dead satellites collide and explode into a storm of debris. Thousands of fragments begin spreading through orbit, drifting directly toward the satellite constellation Dara Kallio is responsible for protecting. She has nine hours. Nine hours to move an entire fleet out of the path of destruction. Nine hours before the company behind the network loses everything. Orbit and trajectory calculations stop being theory and become real impacts and collisions. Dara knows orbital mechanics better than almost anyone. She trusts the numbers because the numbers have never failed her before. She builds the avoidance plan, sends the commands, and watches the first maneuvers work exactly as intended. For a moment, it looks like she has beaten the impossible. Then the situation changes. Because space does not care how good you are. Debris shifts. Predictions fail. Safe trajectories stop being safe. And as the clock races toward dawn over Helsinki, Dara realizes something terrifying. Now the survival of the entire constellation depends on the one thing no algorithm was designed to understand. Everything Dara knows that exists only inside her own head. And before the final decision is made, she will be forced to ask herself a question no calculation can answer: What are you willing to sacrifice when doing your best is no longer enough? A high-stakes sci-fi techno-thriller about orbital disaster, impossible decisions, and the razor-thin line between expertise and catastrophe.
