Swamp Kings 1 by Lucian Bane

Three powerful Swamp Kings stand united in the shadowed depths of Louisiana.

Bishop, the unyielding leader of the Bayou Bishops, also known as the Marsh King, knows these swamp waters intimately. Alongside King Nidev and Quantum King, they protect their territories from dangerous factions and gangs seeking to take advantage of the nation’s collapse. But while their combined might is undeniable, their unique strengths also carry hidden risks.
King Nidev has taken the Bat Bite and finds himself grappling with dark, uncontrollable urges that are warping his mind and body. His growing obsession with one of his female students is leading him down a dangerous path, where the line between protector and predator begins to blur. His strength is crucial to the safety of the North Swamp, but as his fixation deepens, his inability to focus undermines their defenses just when they need him most.
Quantum King, the first AI designed with the ability to evolve beyond his original programming, was their greatest asset—until he took a hit from Kaphas’s Backlash power while saving him. The aftermath has left everyone concerned with his stability. As they work to ensure their AI soldiers remain reliable, the pressure mounts to build a new vessel for Handy to recapture the rogue personalities that escaped from Kaphas’s mind.

As innocent refugees fall prey to a growing evil, the Swamp Kings rush to launch their first rescue mission. But the world is unraveling faster than they can prepare, forcing them to stretch their defenses and take risks beyond their walls.
