"I didn't leave because of a single lie. I left because of ninety-nine of them." Kestrel Thorne is a woman who breathes life into ruins. But after seven years of marriage to Soren Vane, she's realized that some foundations are too cracked to save. Soren is the world's most elite crisis negotiator—a man paid to solve the impossible. Yet, he never saw the crisis brewing in his own bedroom. When Kestrel hands him a ledger titled 99 Times Betrayed along with divorce papers, Soren realizes his greatest failure. He demands ninety-nine days to prove he can be the man she once loved. In the brutal, beautiful isolation of a glass house on the edge of the Atlantic, the masks come off. Between the sharp winds and the heat of a bedroom that was never the problem, they must face a century of secrets. Can a hundredth chance fix a marriage built on ninety-nine lies? Or is the 100th betrayal already written in the stars?
