He was hired to kill her. But her death would unleash a secret that could end the world.

Kaelen is the perfect weapon: a solitary contract killer whose secret ability allows him to experience the final, dying memory of his victims. It's a cursed power he has weaponized, using it to ensure he never kills an innocent. His life is a cycle of calculated death and grim solitude—until a simple contract breaks him.

The target is Elara Vance, a seemingly ordinary archivist. But when Kaelen moves in for the kill, the "imprint" he receives is not Elara's last thought. Instead, he is violently plunged into the final moments of her brother, Jonas—a brilliant physicist murdered to silence him. The dying man's warning is clear: They can't have the catalyst. Erase the drive.

In a split second, Kaelen's professional detachment shatters. Instead of executing Elara, he saves her, turning himself from hunter into hunted. Thrust into a lethal conspiracy, the killer and his intended target form a desperate alliance. Elara holds the key: a stolen hard drive containing "Project Chimera," a terrifying breakthrough that promises to rewrite the very code of life itself—a perfect tool for genocide disguised as a miracle.

Pursued by a shadowy corporation that knows every move they will make before they make it, Kaelen and Elara race across Europe. From the rain-soaked streets of Amsterdam to the high-tech fortress of a Swiss research facility, they must unravel the truth behind the Catalyst. Kaelen must learn to use his grim power not just as a tool for death, but as a weapon for justice, even as it evolves into something far more dangerous than he ever imagined.

Their journey leads to a final, explosive confrontation where the fate of millions hangs in the balance. To stop a global broadcast that would unleash unimaginable horror, they must turn their enemy's trap against them. But in a game where the mastermind knows their every secret, the only way to win is to sacrifice everything they have left.

A high-concept thriller perfect for fans of Blake Crouch and Jason Bourne, Last Thought Before Dying is a relentless tale of redemption, conspiracy, and the haunting power of memory itself.
