Iron Bonds: The Brotherhood of Echo Unit

Lucy
They went to war as soldiers. They came back as brothers. But when the system they fought for betrays them, loyalty becomes their last weapon. Echo Unit was built from broken men — a reluctant captain, a rebellious sergeant, a quiet strategist, a wisecracking soul, and a young recruit with everything to prove. Together, they form one of the most lethal special operations teams in modern warfare. Deployed into a war that no longer makes sense, Echo Unit faces the brutality of combat and the corruption festering inside their own command. When a mission turns into a massacre and the truth is buried, they are marked as traitors and forced to survive behind enemy lines — abandoned, disavowed, and hunted. But in the smoke and blood of a collapsing system, brotherhood becomes their only compass. Each man must face his own demons — guilt, fear, betrayal — while holding the line for the only thing that still feels pure: each other. Years later, when the truth threatens to resurface, the surviving brothers reunite for one last mission — not for orders, not for glory, but for honor. From the trenches of betrayal to the ashes of redemption, Iron Bonds is a powerful tale of courage, sacrifice, and the unbreakable strength of men who refused to die forgotten. It’s not just a war story. It’s a story about what survives after the war.

SG QUINN
Adrian Kaine was once the deadliest operative in Shadow Unit, a black-ops division buried so deep in the government that most agents never lived long enough to speak of it. But when a mission in Kargath Province turned into a massacre, Adrian became the sole survivor, then the government’s most wanted traitor. His squad was slaughtered. Evidence was planted. His name was erased. And those who orchestrated the betrayal made sure he was declared dead. They miscalculated. Eighteen months later, Adrian resurfaces as a ghost in the ruins of his old headquarters, hunting for the truth buried beneath the ashes. But he is not the only one searching. Marcus Hale, his former teammate and supposed friend, now leads a covert kill team tasked with eliminating him. Above Marcus sits Colonel Mason Kade, the official who signed the order that condemned Adrian’s entire squad. And watching all of them from the shadows is a faceless mastermind known only by a single encrypted codename: Cipher. As Adrian follows a trail of classified leaks, dead operatives, and impossible coincidences, he uncovers a horrifying secret: a covert plan known as the Ashen Protocol, designed to rewrite the balance of global power—using bodies like his as the foundation stones. But the deeper he digs, the more the truth twists around him. Old allies hide new agendas. Enemies speak with familiar voices. And the real traitor may be closer than he has ever imagined. Hunted by governments, mercenaries, and a ghost from his past, Adrian must become something colder than a soldier and deadlier than a weapon. He must become the nightmare they tried to bury. And this time… he’s not the one running.

Every fight drags him closer to the edge of madness—every punch, a reminder of the arena that forged him.
