The Wildfire Saga continues:
Nature abhors static and seeks change, for better or worse. The Pandemic strain is mutating in ways no one can predict, and time is running out. Military scientists sprint toward a vaccine, but without the Source they fight a losing battle. Navy SEALs race against foreign invaders to rescue one of the only scientists in the world capable of defeating the flu, but enemies - and traitors - plot their downfall at every turn. Army Rangers struggle to keep the Source alive long enough to give the human race a fighting chance, and rival presidents have brought the nation to the very edge of civil war: Friends and neighbors turn on each other from Boston to San Diego.
The Source, his previous blood, and the fate of the entire world hang in the balance. New allies and new enemies appear, but when the virus mutates, even the bravest heroes will learn to fear...the Shift. The Shift is the second book in the Wildfire Saga and sequel to Apache Dawn.
