Sienna Ross, a quiet community-college graduate who has spent her whole life putting everyone else first, signs a twelve-month private companionship agreement with Julian Cross, a controlling billionaire CEO, to pay for her younger sister's life-saving heart surgery. What begins as a cold transaction slowly turns into real feelings on both sides—but Sienna's toxic family, a scheming socialite rival, and Julian's own inability to see her as anything but "his" eventually drive her away. She rebuilds her life in Santa Barbara as an independent pastry shop owner, and only then does Julian learn that loving someone means letting them choose you freely, not owning them.
