Reina Carlo was forged by the Stingers, a shadowy organization that raised her to be a weapon. Her memories of a family—a mother’s face or a father’s embrace—were long lost, replaced by the harsh discipline and ruthless training of her surrogate family. To her, the Stingers were everything, until betrayal shattered the fragile foundation of her loyalty. Now, Reina walks the streets as the hunter, her mission deeply personal. A man who dared to strip away her last shred of innocence must face the consequences. Her scars are tools, her training a guide, and by sunrise, her vengeance will be complete. But each kill leaves a stain on her soul, no matter how she rationalizes it. She tells herself the trade is fair: she removes monsters, and the world lets her survive another day. Redemption and forgiveness don’t belong in her world—they are luxuries for those unbroken by life. Yet the nightmares persist, whispering of a stolen past and a family that might still exist. Did they abandon her, or did they think her lost? These thoughts claw at her resolve, forcing her to confront a truth she can’t bury: forgetting isn’t the same as letting go. Her pact with Marco Alessandro—a powerful, calculating man—only adds to her turmoil. Their marriage of convenience grants her the resources to find her family and avenge her past. But Marco’s unrelenting gaze and quiet intensity break through her defenses, challenging the walls she’s built. As vengeance, love, and identity collide, Reina faces a choice: cling to the darkness she knows or risk everything for a future she can’t predict. In this world of shadows and betrayal, Reina Carlo fights not just to survive—but to discover who she truly is.
