Countdown to 250: A Rebel’s Collection of Books, Films, and Podcasts

We are just days into the 250th year of American independence. While the Founders wrote everything down, few people have time for dry lectures or dense textbooks. Most of us prefer to learn through the "entertainment principle"—absorbing history through compelling stories. My goal as an author is to inspire you to fact-check me. If my novels drive you to the library to uncover the real history, that is a win. To help you connect with the past, I am launching Countdown to 250: A Rebel's Collection of Books, Films, and Podcasts. This is a curated, multimedia list of the best historical fiction, nonfiction, and movies I have personally vetted.

Robert Connolly and the Spark of Dunmore’s War: An Exclusive Excerpt

Lord Dunmore’s plan was bold, but the carnage it was going to unleash was going to be devastating. Robert Connolly chuckled to himself as he thought about how simple it would be. It made no difference where a person was from, or their culture; humans were the same. Deep down, he knew that all men crave violence. Every soldier in the British Army, and every colonist on the frontier, was nothing more than an expendable pawn in the great game of power played by those who would never set foot in dangerous places. But none of that truly mattered. Connolly was paid well, and he would do as he was told. The other pawns were on their own.
