Maya Ellison always dreamed of a family of her own ... until her fiancé left her at the altar for her own cousin. Heartbroken but not broken, she throws herself into the one thing that still feels safe: her nephew. When her sister's sudden move overseas leaves her stepping in as a temporary nanny, Maya never expects the job to lead her into the orbit of Nathaniel Cole, the cold, guarded billionaire next door raising his late wife's daughter alone. Nathaniel doesn't do warmth. He doesn't do trust. But he needs someone the little girl will actually smile for and Maya is the only one who's managed it. He offers her a temporary arrangement: move in, care for his daughter, keep the tabloids off his back with a fake engagement. Strictly business. Strictly temporary. Except every bedtime story, every shared dinner, every quiet moment in the nursery starts chipping away at the wall Nathaniel built after loss. And Maya, who swore she'd never trust a man's promises again, finds herself falling for the one man who was never supposed to be real. When the truth about his late wife and the real reason he needs a wife on paper.... comes out, Maya has to decide if she's brave enough to want a happy ending she never let herself believe in again….
