The Diamond City (Book Three: The Diamond City Trilogy)

Fresco is finally free of the blue joy forever. Even better, his brother Daniel is alive and clean, the leader of a group fighting the corporation for years. But Fresco faces worse than his own self-doubt and hatred at his weakness. A new strain of Wasteland has hit the streets, one that turns his kind into savage killers. Their only recourse is to invade the project and end it once and for all.
