About The Author
Dan Callahan
Dan Callahan is a retired U.S. Army Sergeant Major and lifelong student of military history, biblical antiquity, and science fiction world-building. His 25 years in uniform shaped not only his leadership philosophy, but also his fascination with how people confront systems larger than themselves, a theme central to his debut novel, The Human Number.
With a degree in Middle East Studies, Callahan’s academic interests span ancient cultures, prophetic writings, and the geopolitical landscapes that continue to shape the modern world. His writing blends these influences with his passion for speculative futurism, exploring how faith, identity, and human resilience endure in times of upheaval.
Today, Callahan works as a Human Resources professional, where he focuses on organizational culture and leadership development. He draws heavily from those experiences to build believable characters, institutions, and conflicts in his fiction.
He lives in North Florida with his family, where he continues to write, study, and imagine the worlds that might come next.
