Phoebe Langley believed her billionaire husband Grant had chosen her against his family, against an arranged engagement, and against every reason to walk away. For five years, their marriage seemed perfect. Then Phoebe discovers that Grant’s endless business trips have been a lie, and that the other woman is her own half-sister, Tessa. Worse still, Tessa is pregnant. When Grant asks Phoebe to be “generous” and accept them both, her perfect marriage turns into a cruel test of love, family, and self-respect. Phoebe must decide whether the quiet woman everyone underestimated is finally ready to walk away.
