A cryptic mathematical formula. A global broadcast. A chilling ultimatum.

When a series of high-profile murders shake the world, each crime is marked by a strange numerical sequence-the Grandi Series. Detective Sarah Martinez is on the trail of a mathematical genius turned eco-terrorist, Donald Klainsky, whose deadly manifesto warns of humanity's impending extinction due to greed and environmental destruction.

But the case takes a devastating turn when Sarah is kidnapped. Her only hope? A desperate, high-stakes rescue mission led by her estranged husband, Ty, and an aging professor, Williamson, who is the only one capable of deciphering the killer's coded messages.

Broadcast live to millions across the world, the search for Sarah leads to the icy wilderness of Alaska, where a horrifying truth awaits. With time running out, the final confrontation will test the boundaries of morality, sacrifice, and the future of life itself.

Is Klainsky a madman, or is he the only one brave enough to show humanity its fate?
