Sable Kilbride built her husband's hotel empire with her own two hands-and her name was never once on the deed. Then she finds a single line item in a budget spreadsheet: $84,000, paid to a design firm that doesn't exist.

Three weeks before their twentieth-anniversary gala, Sable starts pulling the thread-and unravels far more than a shell company. Forged signatures. A safety violation that could kill a guest. And a betrayal that runs straight through her marriage and her oldest friendship at once. Her husband, Sebastian, built his father's dynasty on her design work and never gave her a name on the letterhead.

Her best friend of fourteen years has been keeping a secret that will end them both. And somewhere in the wreckage, an investigative journalist named Callum Farrow is the only person who tells her the truth without managing her feelings about it. Sable has one chance to make this right-not quietly, not through lawyers alone, but standing at a podium in the ballroom she designed, in front of every investor who ever underestimated her. This time, her name goes on the work.
