Anya Volkov is offered as the price of peace.

After eighteen months of bloodshed, the war between the Volkov and Caldero families can only be ended one way: through marriage. Roman Caldero wants a union strong enough to turn a ceasefire into structure. Anya’s uncle wants the war to stop before it destroys what remains of the family. And Anya is expected to walk to the altar and make a transaction look genuine enough for the entire underworld to believe it.

Roman chooses her because she is intelligent, controlled, and impossible to embarrass. Anya agrees because refusal would cost too much. But from the start, she refuses to be a decorative peace offering. She negotiates. She studies the man she is meant to marry. And she makes it clear that if this alliance is going to be built through her, she will not stand inside it blindly.

What begins as a carefully staged marriage soon becomes something far more dangerous. Public devotion turns into private honesty. Investigation turns into trust. And as threats begin pressing in from both inside and outside the alliance, Anya and Roman discover that the most fragile part of their arrangement is also the strongest: the fact that they are beginning to choose each other for real.

But peace built on power always has enemies. When betrayal rises from inside the structure they are trying to hold together, Anya and Roman must decide whether they are only performing a marriage, or building one strong enough to survive the reckoning that is coming.

Vows Under Fire is a dark mafia marriage romance featuring an arranged alliance, strategic attraction, public devotion, private negotiation, and a power couple forced to choose love and loyalty under fire.
