One man’s past may determine the fate of the nations.

GUARDIAN follows Feyzi Çelik, a Turkish-American technologist who narrowly survives the mid-Atlantic crash of Flight XT84 – an apparent terrorist strike. But the truth is darker: semi-autonomous submarine drones known as Kazuars – created in secret by a rogue alliance of Russia, China, and North Korea – are silently waging an underwater war. NATO’s only hope rests in Echo-7, a hidden undersea command base, and in the resurrection of a long-buried military AI project codenamed ARES.
 
As Feyzi works alongside NATO commanders, genetically enhanced dolphins, and autonomous SEV units to activate ARES, the global stakes escalate – and so do questions about his own origin. Because Feyzi isn’t just a survivor. Thirty years ago, he helped create the technology threatening the world today.
 
GUARDIAN blends the global urgency of Tom Clancy, the AI intrigue of Daniel Suarez, and the cinematic suspense of Matthew Quirk. It’s a genre-bending thriller that explores the line between technological evolution and human identity.
