Beneath the skyline’s glitter lies a ruthless empire—
where syndicates clash, kings are forged,
and one wrong move can end generations of power.
Russian, Italian, Irish, Salvadoran…
they all fight for territory.

They all understand that power comes at a price.

But even the strongest rulers fall to one weakness:
The taste of passion.

In the shadows of this brutal world, dangerous men take what they want—and protect what’s theirs with savage devotion.

Whether it’s the hacker king watching from afar, the enforcer bound by rage, or the godfather haunted by his sins…

Each will meet the one thing he cannot control.

Her.

She might be innocent or deadly. Prey or predator.
But when she crosses his path, she becomes his.

And no one takes what belongs to the Syndicate.
