Ruthless Vows

Some vows are spoken with love.
The most dangerous ones are sealed in blood.
Cassian Valieri has spent his entire life preparing to inherit one of the most feared mafia empires in the world. Cold, disciplined, and utterly ruthless, he knows that every decision he makes will shape the future of the Valieri Syndicate. Love has never been part of the equation. In his world, emotions are weaknesses, trust is a liability, and power is everything.
Seraphina Moreau was raised on the opposite side of a decades-long war. As the daughter of the Moreau family, she's learned that survival depends on intelligence, patience, and knowing exactly when to reveal her hand. She refuses to be treated as a bargaining chip-even when her own family demands the ultimate sacrifice.
To end generations of bloodshed, the two rival families forge an uneasy alliance through an arranged marriage. Neither Cassian nor Seraphina wants the union, and both enter it convinced the other is hiding deadly secrets. Every glance is a challenge. Every conversation is a negotiation. Every touch blurs the line between hatred and desire.
But while the world's most powerful crime families celebrate a fragile peace, someone lurking in the shadows has a different plan.
A masked organization begins eliminating trusted allies, anonymous messages expose carefully buried secrets, and an assassination attempt on the newlyweds proves that the marriage was never meant to unite the families-it was meant to destroy them from within.
As betrayal closes in from every direction, Cassian and Seraphina must decide whether to continue fighting each other or stand together against an enemy neither family saw coming. Because in a world where loyalty is bought with blood and betrayal is paid for in lives, one wrong move could reignite a war that consumes everyone they love.
Some vows are made at the altar.
The ruthless ones are made with a trigger pulled, a knife drawn, and blood on your hands.
