Sloane Caraway is a liar.

 

They are harmless lies, she tells herself, to make her own life a bit more interesting. So when she sees a child in tears in a playground one afternoon, she tells the girl's (very attractive) dad she's a nurse and helps him pull a bee sting from his daughter's foot. With this lie and chance encounter, Sloane becomes the nanny for Jay and Violet Lockhart who have everything: a beautiful brownstone house, a daughter in private nursery school, and long summers on an idyllic island just off the coast of New York. Sloane wants to be just like them. She wants their life and she's prepared to lie about almost everything to get it. But Sloane isn't the only one lying, and soon she begins to realise that all that's picture-perfect about her employers hides a much more dangerous truth...
