Jackson Avery has been a single father for the duration of his daughter, Athena's, life. Her mother, Myla, died tragically during childbirth and rests under a nondescript headstone gone unvisited. Jackson, a high-powered stockbroker, needs help with his grown daughter and hires a nanny - April Kepner. April is a nanny by day, lounge pianist and singer by night. The Avery family is not easy to get close to, but she quickly becomes tangled in their web. There are things Athena never learned from her mother that she's desperate to know - and though she's hellbent on keeping her nanny at an arm's length, April might be the only one able to teach her. As she cracks the hardened veneers of both the Avery father and daughter, April finds herself falling for them both. But a nanny isn't a mother, as anyone knows, and April won't find her place - in her job or in the world - so easily.
