Flynn Nightsider and the Edge of Evil - Flynn Nightsider

Break the enchantments. Find the truth. Ignite the revolution. A century ago, the Enchanters defeated the evil Lord of the Underworld, but not before he'd unleashed his monsters and ravaged the earth. The Enchanters built the Triumvirate out of what remained of the United States, demanding absolute obedience in exchange for protection from the lingering supernatural beasts. Sixteen-year-old Flynn Nightsider, doomed to second-class life for being born without magic, knows the history as well as anyone.
Fed up with the Triumvirate's lies and secrecy, he longs for change. And when he stumbles across a clue that hints at something more - secrets in the dark, the undead, and buried histories - he takes matters into his own hands. Before long, Flynn finds himself hunted not only by the government, but also by nightmarish monsters and a mysterious man with supernatural powers . all seeking him for reasons he cannot understand.
Rescued by underground rebels, he's soon swept up in their vision of a better world, guided by a girl as ferocious as the monsters she fights. But as the nation teeters on the brink of revolution, Flynn realizes three things. The rebellion is not what it seems. Flynn himself might be more than he seems. And the fate of the world now rests in his hands.
