When Lily finally leaves her toxic relationship, a job as a nanny at Kewney Manor seems like the perfect solution. There, she can cut herself off from her old life, and never have to see her ex again. The Rowes seem like a model family, and Lily falls instantly in love with her new home. But she can't help feeling that something isn't quite right. Why will nobody tell her about the nanny who came before her? Where does Laurie go at night? And what does Charles really want? As Lily becomes increasingly entangled in the Rowes' lives, she realises that the perfect family may not be all that they seem.
