Captain Calli Chase works as a NASA pilot, quantum physicist, and cybersecurity investigator at the Langley Research Center. On the eve of a top-secret installation aboard the International Space Station—secretly intended to launch a quantum-based network—Calli detects a silent alarm deep beneath the facility. When a contractor is found dead in suspicious circumstances, clues point toward her missing twin sister, Carme, whose own secrets may trigger disaster. With a blizzard approaching and a government shutdown imminent, Calli races against time to prevent sabotage that could derail the mission—and endanger national security. But confronting threats inside and out, she realizes the danger runs deeper than she ever anticipated.
