Matt Forbeck's Brave New World: Revelation

The Truth Is Finally RevealedIn the aftermath of the mass breakout of superpowered deltas from New Alcatraz, fear and chaos grips the United States. Patriot - the leader of the rebellion known as the Defiance - and his friends Street, Lisa, and Charge work tirelessly to help the people in their organization's swollen ranks. When a madman attacks a family of rogue deltas hiding in the Front Range of the Colorado Rockies, Patriot and his friends rush to their rescue.
What they find when they arrive forces them to grab the family and race to Denver, where they wind up in a standoff against Delta Prime, the government agency of superpowered soldiers determined to crush their rising resistance. In the course of this, the second book of Matt Forbeck's Brave New World trilogy, the heroes of the Defiance learn more of the truth about the disappearance of the city of Chicago back in 1976, and what they discover will change the world forever.
