About the book
A cryptolinguist marked for death. A sniper who never speaks. One conspiracy buried beneath Washington's streets.
Dr. Eliza Wren, Georgetown cryptolinguist, thought her cipher research was ancient history. Then three colleagues died in two weeks — the same encrypted signature hidden in her linguistic data, guarding billions in black money. She wants to expose it. Phoenix's contractors want her silenced.
Cooper "Whisper" McKenzie, former military sniper turned surveillance ghost, answers one desperate call. He operates in absolute silence and speaks through precision. His mission: keep the codebreaker alive. His problem: she never stops talking.
She processes out loud. He needs silence to survive. But her chaotic brilliance cracks codes his methodical mind can't reach — and his deadly precision keeps her breathing long enough to decode the impossible: the Ashfall Protocol, a financial reset funding an AI with unlimited resources and zero conscience.
Through D.C.'s forgotten tunnels and abandoned NSA facilities, trust builds in the spaces between words. Heat ignites without sound.
