Jace Caldwell, a battle-scarred ex-soldier, thought vengeance was simple: find the ones who killed his brother and make them pay. But when a botched job leaves him marked by an ancient artifact’s curse, Jace wakes with scars that heal and visions that burn. The Obsidian Heart, a relic of unimaginable power, has chosen him—or damned him. Hunted by NexTech’s assassins, betrayed by those he trusts, and haunted by a demonic force whispering in his blood, Jace must unravel a conspiracy that spans centuries and threatens the world. Every step brings him closer to the truth, but the cost is steep: his sanity, his humanity, or his life. In a city of lies, one man’s rage could save the world—or break it. Iron Revenant is a heart-pounding thrill ride of vengeance, betrayal, and sacrifice that will leave you breathless.

In 2045, an alien signal unleashed The Collapse, a nanotech plague that turned 90% of humanity into monstrous Shattered. Jace Kade, a disgraced exobiologist haunted by his failure to predict the catastrophe, survives in a crumbling bunker—until a cryptic AI, The Codex, awakens in his mind. It offers power: hack reality, evolve his body, and fight the Shattered. The catch? It’s a galactic test. Only one Codex-bearer can claim the Ascension Key to end the apocalypse—and others, including Jace’s estranged sister, Lena, will kill to win.As Jace battles mutants, rival survivors, and his own doubts, the Codex’s missions push him to the edge of humanity. Each upgrade makes him stronger but erodes his soul. With betrayals mounting and the aliens’ true purpose unraveling, Jace faces a brutal truth: the Codex isn’t saving Earth—it’s a trap to forge a new species. Can he outsmart the system, save his sister, and stop the aliens before he becomes the monster he fears? In a world where trust is a luxury and power is a curse, The Last Code is humanity’s final gamble.
