She married a stranger to save her family. He married her to destroy his.

Wren Ashford was never supposed to be the bride. Her family owes the Castellans a debt eleven million dollars deep, and on paper the deal was simple: her younger sister marries Gabriel Castellan, and the note gets paid. Instead Wren walks down the aisle in her sister's place — and Gabriel, learning the truth the moment he lifts her veil, marries her anyway.

Ten years ago his mother fell from a terrace, and the world called it an accident. Gabriel never believed that. He married a stranger to get close enough to find out who's lying. What he doesn't expect is a wife worth trusting — or a secret of her own, inherited from a father who died with the truth locked behind his teeth.

As the marriage that was supposed to be a transaction turns into something neither of them bargained for, the past they're both hiding from starts climbing back up the stairs — and the woman responsible for Isabelle Castellan's death has never stopped watching this family, or deciding who gets to survive what comes next.

A dark, slow-burn romantic suspense standalone about the debts we're born into, the vows nobody consents to, and the terrifying, necessary work of choosing to stay anyway.
