OLD GUN: The Gray Hunter novella collection

by Mark Rogers

Hugo Berenson has spent a lifetime hunting down ex-Nazis and bringing them to justice. Now in his 60s, with a legendary career behind him, he’s gone to ground in Jersey City, living a quiet and anonymous life.

In Gray Hunter, a nine-year-old Hispanic girl goes missing. When the authorities barely raise a finger to find her, the panic-stricken mother seeks out Berenson.

A hunter renowned for tracking his prey.

For never giving up.

In The Youth, Berenson trades the streets of Jersey City for the Florida Everglades, to execute the nonagenarian Nazi commandant responsible for the deaths of thousands of Jews.

In Meadowlands, when Aryan group Combat 27 vows to end Berenson’s reign of retribution, Berenson becomes the hunted rather than the hunter.

Evil flows – from Dachau to the alleys of Jersey City.

One man will stem the tide.

About the author

Mark Rogers spent years watching smart, motivated people lose the same battle over and over: they'd sit down to do meaningful work, and an hour later find themselves somewhere on the internet with no memory of how they got there.

That pattern became the central question of his career. Not "how do we use our phones less" — but why the usual answers don't work, and what actually does.

Drawing on behavioral psychology, neuroscience, and firsthand research into how major platforms engineer engagement, Rogers developed a framework built on one core insight: this isn't a willpower problem. It's a design problem. And design problems require structural solutions, not moral ones.

His first book, Reclaim Your Brain, applies that framework to daily life — covering everything from the neuroscience of dopamine loops to practical environment redesign, deep work protocols, and the specific challenges posed by 2026's real-time AI-generated content systems.

Rogers consults with individuals and organizations on digital productivity and attention management. He lives by the same rules he writes about, which means he's probably not checking his phone right now.
