Lucius Frost built his life with Stella Gibson on three conditions: she would be the perfect girlfriend in public, loyal to him, and a stranger if they ever parted.
For three years she kept that bargain and loved the possessive billionaire who meant to keep her at his side.
She then left the country without begging him to stop her or asking why, and pride kept him away for a year.
Her return puts her outside his world, and when he finds her she says she already belongs to someone else and will take him back only as her secret lover.
Lucius accepts those terms, but danger gathering around Stella drives him to break the rules rather than make her a stranger twice.
