DEA Special Agents Diane Wallace and Charlie Bradon are partners, seasoned veterans used to the grim realities of the drug war. But nothing could have prepared them for Charybdis. What starts as a seemingly routine raid on a cartel safehouse in Juárez plunges them into a nightmare. They uncover a new designer drug, far more sinister than anything they’ve ever encountered—a bioweapon that triggers horrific, irreversible transformations in its users.

When their own team is brutally ambushed, and Diane and Charlie hunted by the very agency they swore to serve, they must rely on their instincts and a shadowy operative named Norman Thiesman, a man who seems to know more about Charybdis than he lets on.

From the blood-soaked streets of Juárez to a secret research facility in Kentucky, Diane and Charlie follow a trail of death and deception. They uncover a conspiracy more terrifying than they could have imagined, a plot to weaponize human beings and unleash a new era of warfare. With the clock ticking, they must expose the masterminds behind Charybdis and prevent a global catastrophe—even if it means sacrificing everything.
