Chad Huntley can't get sick.
When an influenza pandemic kills almost everyone around him, he finds himself on the run, hunted by soldiers and mercenaries, chased across a wasteland of empty houses and dying suburbs as he tries to escape Fort Worth.
Mankind's only hope is for him to partner with a brilliant virologist to find a cure—but not everyone wants a cure for the greater good.
The Source, the first prequel to Apache Dawn, opens a terrifying window on the early days of The Great Pandemic and sets in motion the events of the Wildfire Saga.
