Ex-Heroes — Peter Clines

The first novel in Peter Clines' bestselling Ex series.

Stealth. Gorgon. Regenerator. Cerberus. Zzzap. The Mighty Dragon. They were heroes, using their superhuman abilities to make Los Angeles a better place.
 
Then the plague of living death spread around the globe. Billions died, civilization fell, and the city of angels was left a desolate zombie wasteland. 
 
Now, a year later, the Mighty Dragon and his companions protect a last few thousand survivors in their film-studio-turned-fortress, the Mount. Scarred and traumatized by the horrors they've endured, the heroes fight the armies of ravenous ex-humans at their citadel's gates, lead teams out to scavenge for supplies -- and struggle to be the symbols of strength and hope the survivors so desperately need.
 
But the hungry ex-humans aren't the only threats the heroes face. Former allies, their powers and psyches hideously twisted, lurk in the city's ruins. And just a few miles away, another group is slowly amassing power . . . led by an enemy with the most terrifying ability of all.
