The Tiny Vampire From Outer Space That's Bitey IX - Stacey Carroll - Bog

Marcus may have thought his biggest problem was ensuring that they didn't alert the humans to their food-creation and family expansion activities, while they worked on taking over Earth, but a new threat is on the horizon. The Space Agency wants to recreate Marcus' spaceship engine fuel, which requires massive amounts of space dust. The problem with that is that Earth's atmosphere doesn't kill a nervous system destroying bacteria that's present in the space dust. Can Marcus delay them until he can take over the planet or will he have to change Earth's atmosphere and hope he doesn't kill every living thing on Earth?
