About This Book
The cold hum of the spaceship fills the air, mixing with the faint scent of burnt metal and fear. Thea, Coen, and Nova thought they were finally safe, but the shadows around them whisper of a new danger—one that could destroy the whole galaxy. As the nightmare creeps closer, their courage is the only weapon left to fight back.
