Vows of Ruin: A Dark Billionaire Revenge Romance

He needed a debt paid in blood and ruin. I became his sacrifice.

Sera Hargrave thought burying her father would be the end of her nightmare. Instead, three men in black suits arrive at her door with a contract bearing her father’s signature—and her name.

The terms are absolute: marry Rhys Castor within thirty days, or her family loses everything. Not just her home. Not just her father’s shattered company. But the medical foundation keeping her younger brother alive.

She has no choice. But Rhys isn’t just enforcing a contract—he’s settling a fifteen-year vendetta.

Rhys Castor is a self-made tech billionaire and the youngest member of the Consortium—a shadow society of powerful elites who rule from the dark. He spent his life climbing to the top for one reason: to destroy the man who ruined his family. Vincent Hargrave’s convenient death cheated Rhys of his revenge, so he’ll take everything Vincent loved instead. Starting with his daughter.

He plans to marry her, break her, and dismantle the Hargrave legacy piece by piece.

What he doesn’t expect is a wife who refuses to kneel.

What he doesn’t know is that Sera has been hunting the same secrets he has—and her father’s murder is only the first layer of a deadly Consortium conspiracy.

Trapped in an arranged marriage where trust is a liability and desire is a weapon, two sworn enemies must decide what they’re willing to sacrifice. Because in the world of the Consortium, falling in love is the most dangerous game of all.
