Lady Caroline Darrow dreams of a marriage built on mutual respect and partnership, not duty and convenience. But when she finds herself betrothed to the brooding and secretive Julian, Viscount Osborne, she quickly realises that their arranged match will test her patience—and her heart. To create the life she envisions, Caroline must navigate meddling family members, society’s expectations, and a husband who keeps his emotions as tightly guarded as the sprawling estate he loves. Julian Osborne has long protected himself behind walls of duty and control, determined to preserve his family’s legacy at all costs. But his new fiancée’s wit, warmth, and undeniable charm threaten to dismantle the carefully ordered life he’s built. To win Caroline’s trust—and her love—Julian must confront the ghosts of his past and open his heart to a future he never dared hope for. As tensions rise and secrets are revealed, Julian and Caroline must learn to trust one another if they hope to turn their union of necessity into a love that lasts forever. The fourth and final book in the Darrow Sisters series.
