It is a story about growing up told from the point of view of a woman (Scout/ Jean Louise Finch) looking back almost 20 on her youth as a little girl living in a small town in the 1930's. She tells the reader of the many events and lessons she experienced with her brother and a good friend (Dill Harris) over the course of 3 years.
The novel is renowned for its warmth and humor, despite dealing with the serious issues of rape and racial inequality. The narrator's father, Atticus Finch, has served as a moral hero for many readers and as a model of integrity for lawyers. One critic explains the novel's impact by writing, "In the twentieth century, To Kill a Mockingbird is probably the most widely read book dealing with race in America, and its protagonist, Atticus Finch, the most enduring fictional image of racial heroism."
I wouldn't be able to answer question completely becuz it has so much to say but I fully recommend you to read this book it really makes you think. If you like that book I recommend you reading "The Outsiders" it's a very beautiful book
