The explosive conclusion to the New York Times bestselling trilogy that began with Infected and Contagious.
The alien intelligence that unleashed two horrific assaults on humanity has been destroyed. But before it was brought down in flames, it launched one last payload-a tiny soda-can-sized canister filled with germs engineered to wreak new forms of havoc on the human race. That harmless-looking canister has languished under thousands of feet of water for years, undisturbed and impotent...until now.
Days after the new disease is unleashed, a quarter of the human race is infected. Entire countries have fallen. And our planet's fate now rests on a small group of unlikely heroes, racing to find a cure before the enemies surrounding them can close in.
