Something— probably man-made and probably started by the Red Hammer cartel—is altering the Earth's atmosphere, accelerating climate change with a vengeance. The air is becoming toxic, unbreathable. And it's spreading. People have died, and more might die if the changes aren't stopped. Looks like Quantum Corps has its hands full again. Lieutenant John Winger leads his beleaguered nanotroopers into combat, on battlefields across the globe and inside the world of atoms and molecules. Second episode in the Tales of the Quantum Corps.
