Countdown to annihilation.
An Alliance asset is found brutally murdered. Classified chiral material has vanished. Shadow Recon pilot Micah Case is the only human in existence who is immune to the weapon the Akkadians have developed using the stolen samples. 
Now, a member of the team has disappeared. Micah must find his missing teammate, track down the samples, and destroy the Akkadian laboratory before they unleash the deadly package. If they can't stop it in time, it's not the end of the world. It's the end of all life as we know it. 
Includes Ambush in the Sargon Straits, a bonus novella from the Biogenesis Wars series.
