The fate of the world is in the hands of two men. One is prophesized to end it. The other must save it in an apocalyptic thriller by Wall Street Journal bestselling author Jeff Wheeler.

If the end-of-the-world prophecy is true, a vengeful descendant will reign with blood and fury. The planets are already aligning.

For Jonathon Roth and his family, a vacation in Cozumel became a nightmare. Pawns in a deadly ritual, Roth and his children barely escaped with their lives, and with the secrets of mastermind Jacob Calakmul. Calakmul’s endgame: to fulfill the Jaguar Prophecies—the foretelling of an inevitable Armageddon, one that will destroy entire nations. The key to stopping it is to retrieve an ancient codex—if Roth can decipher it.

From a museum in Dresden where the mysterious codex is on display to the Roths’ Montana home in the dead of winter, no place is safe from Calakmul’s reach. Obsessed with the legends of the magic of the Maya, Roth knows Calakmul’s powers are real. Roth’s own daughter possesses them too. As Calakmul and his henchmen close in, Roth and his children are running for their lives.

In a prepper’s lair in the Montana mountains, Roth must piece together a terrifying puzzle to stop an apocalyptic vision from coming true. If it’s not already too late. Because the countdown to the end-time has already begun.
