As the summary in the book stated, "they (the children) begin to learn that life is not as straight-forward and as fair as it seemed through the eyes of their childhood...and how people react when they are forced to choose between …

…those of lower status and different backgrounds, with the main attention on people like Boo Radley and Tom Robinson. Told through the simple point of view of Scout, a child barely 10, the novel engages readers in deep thoughts about the unfairness towards the innocent people who have committed no crime except that of their background. Prejudice and discrimination is thus presented in a truthful manner through various incidents of Harper Lee's To Kill a Mockingbird.
