The Callaghan Series

By Deborah Ettinger & Tom Johnson

Bound by blood. Divided by the law. Hunted by the city that made them.

About the Series

One Loyal Family. A City That Hunts.

Bound by blood and forged in the crucible of a brutal New York orphanage, Sean and Colleen Callaghan share a loyalty nothing can break. From the eve of the First World War to the smoke-filled aftermath of the Second, their story tears through a raw, unapologetic city — where survival is bought with grit, ambition, and every moral compromise in between.

As the decades turn and the nation reshapes itself, the siblings build rival empires on opposite sides of the law — one fortune raised in the shadows, one in the light — until a single act of violence sends them both running for their lives.

Fiercely Loyal Rating

Sean Callaghan

King of the Waterfront

From petty street theft to Prohibition-era bootlegging, Sean claws his way up until he commands the city’s rough-and-tumble waterfront docks — building an empire in the shadows, one dangerous deal at a time.

Colleen Callaghan

Queen of the East Side

Colleen turns an illicit back-alley speakeasy into the most coveted address on the East Side — pouring drinks for high-society elites, crooked politicians, and underworld kingpins at the very same tables.

When Loyalty Becomes a Death Sentence

Their rise collides with catastrophe when Sean is framed for murder and sentenced to the electric chair. Saved at the last hour by Colleen’s daring gambit, he vanishes into exile with a target on his back — hunted by a vengeful NYPD detective, a ruthless contract killer, and the Mafia. When they can’t find him, they come for Colleen, dragging her into a shadow war against mob boss Frank Costello and a web of corruption that runs all the way to City Hall.

In the dark heart of mid-century New York, every alliance has a price — and loyalty is the only currency worth dying for.

Fiercely Loyal

Where the Streets Draw Blood

5.0 · Amazon & Goodreads · 418 pages

Irish tough guy Sean Callaghan and his sister Colleen carve out rival empires in the criminal underworld of early-twentieth-century New York — until a beautiful woman betrays him and a crooked cop sets his sights on revenge.

A sprawling, propulsive crime epic drawn from the real lives of the authors’ mother and uncle: a brutal orphanage, Sing Sing prison, the Spanish Flu, Prohibition bootlegging, and the gangsters who ruled the waterfront. Spanning the eve of the First World War to the smoke-filled aftermath of the Second, it is a story of family, betrayal, and the fierce loyalty that binds two siblings against a city determined to break them.

“I was gripped from page one. Prose, pace, tone and plotline were all excellent.”

— Lenny, Amazon

“A classic story with vivid imagery and feeling for New York City. I felt transported back in time.”

What Drives the Story

Themes at the Core

The series doesn’t flinch. These are the forces that shape every page.

Fierce Loyalty

Blood before everything. The bond between Sean and Colleen is the spine of the series — tested by danger, betrayal, and the weight of survival.

Betrayal

The deepest wounds come from those closest to us. Sean’s world is undone not by his enemies, but by someone he trusted with his heart.

Resilience

From an orphanage run by cruel nuns to the prisons and waterfront gangs of Depression-era New York — the Callaghans do not break. They adapt.

Identity

Who are you when the world tries to define you? Sean and Colleen refuse the roles forced on them — and build their own.

Power & Corruption

The cops are crooked, the bosses are ruthless, and power is the only currency that counts on the waterfront.

Survival & Love

There is love woven through the danger — the love between siblings, the pull of romance, and the fierce will to stay alive.

A native New Yorker and the emotional core of the partnership, Deborah is a graduate of St. Vincent’s School of Nursing and Hunter College.

Tom Johnson

Native New Yorker · Veteran · Storyteller

Deborah's brother and a fellow native New Yorker, Tom studied English Literature at Fordham University before serving as a U.S. Army infantry officer in Vietnam, where he earned the Combat Infantryman’s Badge and the Bronze Star. He went on to become a Registered Respiratory Therapist and an Associate Professor at Long Island University — a decorated veteran and published academic author.

That lived experience gives the series its gritty pulse — the waterfront, the neighborhoods, the gangs, the grief. Writing from the true story of his mother and uncle, Tom sets out not just to tell a story, but to honor the people who survived what most couldn’t. Together, Tom and Deborah have built a series that is as much a family memoir as it is a crime saga — a tribute to resilience, loyalty, and the city that forged them both.
