Dennis J. Dunn graduated from John Carroll University and received a PhD in history from Kent State University. He taught at Texas State University where he was named a Regents and University Distinguished Professor of History. His research interests include books on the Catholic Church in Soviet Russia, American-Soviet relations, and the relationship between politics and religion in the twentieth and twenty-first centuries.. In 2021 he turned to writing historical fiction in the thriller genre, inaugurating the Posse Series with the publication of The Russian Riddle: Stalin's Deadly Date with Destiny. It drew upon his deep interest in the history of World War II, the Cold War, the rich Anglo-Hispanic culture of Central Texas, the Catholic Church, and Russia. Red Missiles in Cuba is Book 2 in the Posse Series, and it tells the largely overlooked story of the most dangerous time ever in the history of the world when nuclear annihilation was barely avoided. for  He lives in Texas with his family.
