Bulletproof Hearts

Fifteen years ago, Kai Bardin's world was shattered by violence and loss. Now a successful prosecutor, he's forced to confront the ghosts of his past when his estranged sister Jane sends a desperate midnight message and vanishes without a trace. Drawn back to a city haunted by old blood feuds and dangerous secrets, Kai follows a trail of cryptic clues-missing babies, political conspiracies, ruthless criminals-only to find himself face-to-face with Kirin, the boy who once saved his life and is now a feared assassin hardened by betrayal.

As enemies close in and the truth behind Jane's disappearance unravels, Kai and Kirin must confront the past and decide how much they're willing to risk for the people they once loved. Bulletproof Hearts is a story of loyalty, redemption, and the relentless search for those who matter most-no matter how many years or scars stand between them.

"Shoot me if it makes you feel better," Kai said. "But promise me one thing... Promise me you will find my sister and take her home."
