About the author

From an early age, I was drawn to books. When my parents took me to the shopping mall, they’d drop me off at the bookstore and return hours later to find me still wandering the aisles, lost in pages. At my grandmother’s house, I was captivated by her set of World Book Encyclopedias—each visit meant pulling a new volume off the shelf and discovering something I hadn’t known before. It was clear even then: I had a deep love for reading.

​Over the years, that love turned into a passion for collecting and devouring books, especially in the realms of history, historical fiction, and thrillers. For a long time, I carried story ideas in my head, unsure if I’d ever write them down. Eventually, I found the courage to begin—transforming scattered thoughts into pages, and pages into stories. Writing became not just a creative outlet, but a natural extension of the curiosity that started all those years ago in bookstores and encyclopedia pages.

​I’ve had the opportunity to travel to many parts of the world and have lived and worked in several U.S. states, including Michigan, Illinois, Texas, and California. Beyond writing, my interests span the arts, sports, aviation, and education—each offering its own inspiration and perspective that continue to shape my work and worldview.
