Luke Vance is an elite forensic structural engineer and high-stakes auditor for the Department of Energy, a man who views the world through the cold, uncompromising lens of physics and mathematics. Operating in the shadows of the nation’s critical infrastructure, Vance is called in only when the numbers on the global ledger stop making sense—when “Ghost Loads” and anomalous frequencies suggest that energy is being systematically siphoned from the grid. His mission is the Final Audit: a desperate, across-the-globe race to track down the Spillway Cipher, a rogue algorithm designed to manipulate the fundamental laws of thermodynamics and collapse the world’s power systems. Armed only with his deep technical knowledge and a veteran’s instinct for survival, Vance must reconcile the planet’s energy deficit before the encroaching entropy triggers a permanent, global blackout.
