Once every year, beneath a city that sleeps unaware, the monsters of the underworld gather.

Hidden beneath an abandoned cathedral lies The Obsidian Hall—a palace of black marble, crimson velvet, crystal chandeliers, and whispered betrayals. Cigarette smoke curls through the air as violins play over the clinking of whiskey glasses and casino chips. Poker tables decide the fate of empires. Roulette spins determine fortunes. Every smile hides a threat, and every handshake conceals a knife.

This is The Summit.

The only night where the world’s most powerful Mafia families meet to divide territories, forge alliances, arrange political marriages, settle blood feuds, and decide who will rule the criminal world for another year.

Around the grand table sit the heirs destined to inherit kingdoms built on violence.

Mikhail Volkov, the cold Wolf Prince.

Lorenzo De Luca, dangerously charming and impossibly manipulative.

Nikolai Sokolov, who hunts rivals for sport.

Damian Ashford, a master of secrets and calculated ruin.

Rafael Moretti, reckless enough to laugh in the face of death.

Each believes he is untouchable.

Each sees every other heir as either a rival… or prey.

Yet none of them can ignore the empty throne reserved for the oldest and most feared empire of them all—

The Blackthorne Family.

For decades, one mystery has haunted the underworld.

The Blackthornes have never revealed an heir.

Rumors spread every year. Some believed there wasn’t one. Others whispered the heir was hidden because they were too dangerous to exist in public.

No one knew the truth.

Until tonight.

The orchestra falls silent.

Roulette wheels stop spinning.

Conversations die.

The Blackthorne patriarch rises, his cane striking the marble floor once.

“You mistook our silence for weakness.”

His gaze sweeps across the room.

“You believed my empire had no successor.”

A slow smile.

“I simply wasn’t ready to unleash them.”

The towering doors behind him open.

Footsteps echo through the hall.

Calm.

Steady.

Unhurried.

Every heir instinctively stands.

Not out of respect…

But because every instinct they possess senses danger.

Then you step into the light.

The Blackthorne family’s greatest secret.

Its hidden heir.

You.

Silence crushes the room.

In a single heartbeat, decades of alliances become fragile. Every carefully balanced rivalry begins to fracture. The underworld itself seems to hold its breath, as though your arrival alone is enough to promise chaos.

Some patriarchs immediately begin reconsidering alliances.

Others quietly signal their bodyguards.

Some are already wondering whether you should be welcomed…

Or eliminated before sunrise.

But it isn’t only ambition burning in the room.

It’s obsession.

Mikhail watches you with unsettling focus, already seeing you as someone he refuses to lose to anyone else.

Lorenzo smiles like he’s discovered the one person he can’t effortlessly charm—and now desperately wants to.

Nikolai looks at you the way a predator watches another predator, thrilled by the possibility of finally meeting his equal.

Damian is already rewriting every plan around you.

Rafael can’t hide his grin, delighted that the underworld has finally become interesting again.

In this world, love isn’t gentle.

It’s possessive.

Jealous.

Violent.

A tool as dangerous as any weapon.

One dance can become an engagement.

One kiss can spark a war.

One rejection can leave entire families in ruins.

Tonight, the Blackthorne heir has finally appeared.

And every king in the room realizes the same terrifying truth—

You’re no longer just the most powerful prize in the underworld.

You’re the spark that could set every empire ablaze.
