edit data

War didn’t end the world. It uncovered something older.
And it’s waking up.

Garrett Holt writes post-apocalyptic military thrillers that blend modern warfare, ancient relics, and cosmic horror. His work follows elite operators facing threats that don’t follow the rules of war and never should have been found.

With a background in history, political science, and intelligence, and current work supporting U.S. Navy programs and operations, Garrett brings a grounded, realistic edge to global conflict scenarios.

His debut novel, Siege of the Forgotten Order, is the first entry in an expanding series exploring relics, gates, and forces beyond human control.
