The story of Boondock Saints is expanding, this time in book form as the creator of the film is launching a prequel novel next month.
If you’ve been itching for more Boondock Saints, you’re in luck as the filmmaker behind the cult classic is bringing them back thanks to a new novel: Blood Origin.
In The Boondock Saints, Volume 1: Blood Origin, Duffy delivers a pulse-pounding Boston crime thriller that traces the origins of brothers Connor and Murphy MacManus, who slip across the Canadian border chasing the promise of America only to land in a city where survival means learning fast—or dying faster.
Through their connection with Rocco, a Mafia foot soldier and their best friend, the MacManus brothers are thrust into Boston’s ruthless underworld. Each alley hides a threat, every handshake conceals a blade, and every act of justice demands a darker act in return.

But this is more than a story of crime and vengeance. As the brothers hunt for the father they never knew, they uncover a violent legacy carved into their own bones. The journey is one of brotherhood, betrayal, and the moral minefield of vigilante justice—forcing readers to decide for themselves: Saints, sinners, or something in between.
Duffy expands the world he first brought to life on screen with this debut novel. Fans of the film and lovers of crime thrillers alike will find themselves immersed in the gritty streets, morally complex characters, and explosive suspense that define Duffy’s signature style. Steeped in Irish-Catholic noir, this novel delivers unforgettable characters and a cinematic reading experience that will resonate with fans of crime fiction, cult classics, and action-packed storytelling.
The Boondock Saints, Volume 1: Blood Origin is available for preorder in eBook and audiobook formats via Audible, Amazon, and Apple Books now, and will launch on October 21st.
