Thirteen-year-old Amelia and the young engineer Greeny stowed away to join what was supposed to be a simple scavenging job. But after an accident strands their ship, a group of hostile aliens boards the vessel. Now the only crew members left alive are Amelia and Greeny. The two must sneak around the wrecked ship, make repairs, and escape-before they run out of air, and before they're discovered by the deadly invaders.
