On the night an anonymous video shatters four years of marriage, Isabelle learns two things in the same breath: her husband, Adrian, has been unfaithful for longer than she can bear to count, and someone in his own family wanted her to know it. That someone is Nicholas Marchetti, cold, calculating, and the one man in the family who has never pretended to like her. He didn’t send her that video out of kindness. He sent it because Adrian’s lies are about to cost the Marchetti Group everything, and Isabelle just became the only person who can help him prove it.

Trapped in a marriage built on debt she didn’t know she owed and secrets that reach back three decades, Isabelle has two choices: stay and disappear into a gilded cage, or align herself with the brother who once looked at her like an enemy, and now can’t stop looking at her at all. As old family hatred collides with a desire neither of them wants to name, Isabelle and Nicholas are pulled into a war for the Marchetti empire where loyalty is currency, love is leverage, and the only unforgivable sin is falling for the wrong Marchetti.

A forbidden romance of betrayal, family empire, and the brother who was never supposed to want her.
