About This Book
The sharp beep of alarms cuts through the thick hum of the spaceship as Kady races against time. Outside, stars flash by, but danger is closing in fast—enemy ships, a spreading plague, and a mysterious AI that might not be on their side. In the middle of chaos, Kady and Ezra face secrets and fears that could change everything.
