Since the Tragedies, Henry Long doesn't have much: just an annoying low-watt buzz from his makeshift heart transplant, skinny arms, and a dusty library attic from which he charts the reconstruction of the Green Zone, the last habitable neighborhood of his ruined coastal city. While his parents work on making the Green Zone independent from a federal government that appears to have abandoned them, Henry's feels similarly abandoned--that is, until he discovers a refugee artists' colony called the Other Side. When the federales don't take kindly to the Green Zone's attempts at secession and kidnap Henry's parents, Henry and his new renegade friends--including one very courageous girl with whom he's shared one truly shocking kiss--are forced from the colorful streets and underground rock clubs of the Other Side to an overcrowded capital city on the verge of collapse.

As Henry uncovers more about the conflicting forces that run his world, he realizes that not everyone is who they seem to be--including himself. In The Loudness readers will be propelled into an electrifying world where superheroes emerge from the unlikeliest people.
