A ruthless mafia-and-finance thriller where loyalty is tested and the numbers can kill.
A high-stakes rescue mission unfolds under federal surveillance, with a financial meltdown minutes away.

A blood oath. A collapsing bank. One debt with no way out.

Decades ago, David Grasso saved Mitchell Roth’s life and bound him to a code of silence known as the Omertà. Now Grasso, the head of Mercantile International Bank, is calling in that debt.

Mercantile International Bank is hours from collapse. Toxic Venezuelan bonds are dragging it under, the FBI is closing in, and if it fails—it could shake the entire global economy.

Mitch has rebuilt his life, but he can’t outrun what he owes. To get Grasso out alive and stop the collapse, he pulls his team back together: Barrett Johnson, the strategist with a mind for war, and Sam Saxon, the assassin they call the Hangman.

The mission? Easy to explain. Almost impossible to survive. Get one of the most recognizable men in New York out from under federal surveillance, then step into the lion’s den and save the bank from the inside.

They have hours to pull Grasso out and stop the collapse—before the Feds close in and the world’s economy follows.

Twist-filled, ruthless, and high-stakes, The Omertà Covenant is the third book in the Barrett Johnson espionage thrillers series. Perfect for fans of Daniel Silva, Brad Thor, Vince Flynn and The Godfather.

REVIEWS Icon
Max Sinclair has lived through the kind of chaos most only see in headlines—terrorist attacks, coup d’états, uprisings, and the grinding reality of absolute poverty. He’s witnessed the best and worst of humanity, surviving in places where danger isn’t just a possibility—it’s a way of life.
After years navigating the high-stakes world of Wall Street and nearly three decades in the international economic arena, Max took those raw, firsthand experiences and turned them into gripping fiction. His novels drop readers straight into the action, blending pulse-pounding storytelling with the hard truths of power, money, and survival.
Stranded in Madrid during the 2020 pandemic, Max began writing in earnest, inspired by his son and sharpened by masterclasses with James Patterson, Dan Brown, and Stephen King’s On Writing. His debut thriller, Undisclosed Location, was crafted across continents, shaped by his deep knowledge of finance’s shadowy corners and a lifetime of adrenaline-fueled reality.
Now deep into his seventh novel, set for release in July 2025, Max continues to create stories that don’t just entertain—they immerse, haunt, and leave readers questioning what they thought they knew about the world.
When he’s not writing or crunching numbers, Max explores mountains, sails warm seas, and shares his adventures with Flora, his loyal dog. His stories are more than fiction—they’re a testament to a life lived on the edge.
