This is one of those books that you will love or hate. Now You're One of Us is a slow, suspenseful story that revolves around Japanese culture. In a way, I think it is the various cultural elements that add to the plot and move it forward and thus, you have to keep it in mind, in order to enjoy the novel.
The story is about a woman, Noriko, who becomes part of a large family when she marries one of their sons, Kazuhito. As she gets used to the quirky ways of living with more folks in one house, she starts worrying about them. More specifically, she thinks that they have dark secrets and that no one is what they seem.
