About This Book
The sharp wail of the siren fills the air, vibrating through the metal walls of the Star of Empire. Passengers scramble, hearts pounding, as alarms flash and the ship shudders—yet Zak and Tash stand frozen, trapped inside with no way out. The eerie silence that follows is broken only by strange, unsettling sounds... and the feeling that something is watching them.
