James Mace was born in Edmonds, Washington, and grew up in Meridian, Idaho. He joined the United States Air Force out of high school, and three years later changed over to the Army. He spent a career as a soldier, including service in the Iraq War.
In 2011, he left his full-time position with Army Guard and devoted himself completely to writing. His series, Soldier of Rome - The Artorian Chronicles, has been a best-seller in ancient history on Amazon Kindle. His latest, Forlorn Hope: The Storming of Badajoz was his first non-Roman work.
