When self-made billionaire Sienna Cross walks into Manhattan's most exclusive gala, she has one goal: destroy the man who abandoned her five years ago when she was too poor to matter. But tech CEO Julian Thorne is hiding a secret that shatters everything—the daughter Sienna was told died at birth is alive, and he's been raising her all along. One explosive encounter in his penthouse later, Sienna faces an impossible choice: pursue the revenge she's spent years planning, or fight for the family stolen from her by lies, money, and a conspiracy that reaches deeper than she ever imagined. As a ruthless matriarch moves to bury the truth and a custody battle turns into all-out war, Sienna must decide what she's willing to sacrifice—and whether the man who betrayed her could be the only ally she has left. In a world where power is everything and the truth can be bought, some battles can only be won by risking it all.
