Welcome to My World

I’ve been telling stories for as long as I can remember. A surprising number of them have made it into print—fifteen novels so far, which still surprises me a little when I say it out loud. I live in the woods nears Stockton, New Jersey, a small borough on the Delaware River. The kind of place that inspires mysteries, thrillers and horror in the towns and countryside.

My longest-running series is The Kyle Callahan Mysteries—character-driven, funny in places, dark in others, and rooted in lives you might never expect to be troubled by murder. I also write the Marshall James Thrillers series and the Maggie Dahl Mysteries, each with their own voice and world.

More recently I’ve been working in horror and psychological thriller—territory I find endlessly compelling. And my forthcoming (October, 2026) Devil’s Wood is a supernatural thriller set in nearby Lambertville, drawing on modern small town life and ancient horror.

Through Your Write Path, I offer workshops and coaching for writers at every stage—beginners who’ve never shown anyone their work, experienced writers who’ve hit a wall, people who want to tell the story of their own lives. “Every life is a story, and each of us is the storyteller.”

My imprint Vivid Press publishes annotated editions of public domain classics—recent titles include Carmilla, The Willows, and Gaston Leroux’s The Mystery of the Yellow Room. Stories matter.

Look around, you’ll find much more here, and thanks for stopping by. – Mark
