It's the end of everything . . .

The greatest heroes of the Commonwealth are gathered in the breach for one last fight. The Transformation Virus rages through human space like a wildfire, changing ordinary men and women into psionic demi-gods, bent on destruction and conquest.

The government has fallen, the military is helpless and the fate of humanity rests in the hands of a collection of unlikely saviors. Sandi Hollande, disgraced war hero. Kara McIntire, cold and calculating master spy.

Randall Munroe, corporate mercenary. And Caleb Mitchell, the deadliest man alive. Together, they make a stand against the darkness, but will their only hope for victory be in risking the destruction of all they hold dear?
