Martin "Marty" McIsaac was born and raised in Boston before his family moved to the suburbs when he was ten. The oldest son of a policeman and a nurse, Marty grew up in a household where service and duty to community and country weren't just values — they were a way of life. That foundation shaped everything that followed. Over the years, he wore many hats: soldier, police officer, and ultimately special education teacher — a career path that speaks as much to his patience and character as it does to his range of life experience.

​

It's no accident, then, that when Marty finally sat down to write, he reached for a story rooted in history, duty, and the question that drives every great "what if" — what would you do if you had the chance to make it right? That question became the heartbeat of the Marking Time series, a gripping blend of historical fiction and time-travel speculation set against the backdrop of the American Civil War. Two modern teachers find themselves dropped into 1861 with knowledge no one around them possesses — and a choice no one should have to make.

​

Now retired and living in Florida with his wife, Eleanor, and their two inexhaustible Schipperkes, Barnum and Bailey, Marty continues writing—and stubbornly participates in numerous age-inappropriate activities, much to the delight of local medical facilities. The Marking Time series is now available on Amazon, with Book 3 and an audio version in production.
