About the Author

---

Kevin Gillen is a retired federal officer and graduate of the University of Maryland whose career took him around the world, where he explored legendary ancient sites, including the Great Pyramids of Giza, Petra, and Angkor Wat.

These experiences ignited his fascination with lost civilizations, hidden knowledge, and the mysteries of humanity’s past—fueling the creation of Echo of Atlantis.

Blending science fiction with epic fantasy, Kevin writes high-stakes, action-driven stories where ancient secrets collide with modern forces, and nothing is ever as it seems. Influenced by classic mystery and thriller storytellers like Encyclopedia Brown, The Hardy Boys, and Robert Ludlum, his work combines suspense, discovery, and relentless pacing.

His debut novel, The Ūmdëdŭ Codex, is the first installment in Echo of Atlantis, a six-book series that promises readers a thrilling journey through hidden worlds, powerful conspiracies, and revelations that could reshape humanity itself.
