Kate Treanor gave up hope of having a family of her own when her fiancé died three years ago. But miracles—and mistakes—happen. After a scorching one-night stand with a stranger leaves her pregnant, Kate's determined to raise the baby by herself. But when she encounters the criminally charismatic baby-daddy at her best friend's wedding, she's torn between getting him to sign away his parental rights and getting him back in bed. Playboy Oliver Mercier is thrilled when Kate reappears in his life—until it turns out she's more interested in having him forfeit his responsibilities than repeating a night he's never forgotten. Oliver is faced with upending his lifestyle to become a co-parent with the baby-mama he'll never stop wanting. He won't stop fighting for her, because he can't fight this feeling.
