Every morning, Evie counts her little sister's breaths before she counts the bills.Steady. Shallow. Too thin.The vineyard is her grandfather's hands in the soil and her father's ashes under the oak.The oxygen concentrator hums down the hall.And the operating loan is bleeding interest she can't outrun.Evie has held it all together with bare feet on cold tile and a stubbornness that won't quit.Then a billionaire walks into her ruin and offers to buy what's left.He's cold. Exact. The kind of man who responds to spreadsheets, not passion.He's also the only thing standing between her family and losing everything.So she takes the job. The deal. The unbearable proximity of working under a man who notices the dirt on her hands and the fear she hides behind dark roast and bad jokes.Workplace tension turns to something warmer.A grumpy magnate and a sunshine woman who refuses to break.A friendship that deepens, slow as a barrel aging, into something neither of them planned.Then trust catches fire—an invoice, a betrayal, a sister who falls apart—and everything Evie built threatens to crush her in the parking lot where no one can see."Let me carry it," he says. "You don't have to hold all of this alone."But Evie has been alone so long she's forgotten how to let anyone in.With the harvest festival looming and her family fracturing around her, she has to choose between the armor that's kept her standing—and the man who wants to help her build a home from the ruins.Some things die before they're ready.
