One Summer at Calderayne. The Calderayne Billionaires, #1

He hired her to care for his daughter. He never expected her to dismantle every wall around his heart. Romilly Sayer arrives at Calderayne House desperate for a fresh start and a summer job. Instead, she finds seven-year-old Leni outside a third-floor balcony railing, risking everything to recover the last gift her mother left behind. Romilly's quick thinking saves her-and earns her a three-month position as nanny to the billionaire's grieving daughter.
Callan Calderayne has built his life around control. After losing his former wife, the powerful single father trusts schedules, security, and carefully written contracts far more than people. Romilly refuses to be intimidated by his wealth or his rules. More importantly, she sees the frightened child behind Leni's defiance and gives her something no one else has managed to provide: honesty without abandonment.
As the summer unfolds, Romilly becomes the heart of a household that has forgotten how to heal. But a visitation battle, buried family secrets, and a dangerous man from Romilly's past threaten the fragile trust growing between them. The closer Callan comes to protecting her, the more Romilly fears that safety could become another kind of cage. Falling for her employer would cross a line neither of them can ignore.
Yet when the contract ends, Callan and Romilly must decide whether what began as one summer at Calderayne can become the home-and the family-they never expected to find. One Summer at Calderayne is an emotional, slow-burning contemporary romance featuring a billionaire single father, a courageous live-in nanny, found family, healing, workplace tension, and a love built on trust rather than control.
