Marissa is a single mother who teaches people how to care for infants. While teaching, she meets a new student, the gentlemanly Alec. He lost his beloved wife a year earlier and decided to take Marissa’s course to learn how to care for his daughter. But after seeing Marissa pacify his daughter, he asks her to become his live-in babysitter. Marissa already has her hands full with work and her own son. But she also has to move out of her home, so she accepts the job and moves in with Alec. She promises herself she won’t become romantically involved with him, but that promise may be harder to keep than she thinks.
