Third-person omniscient allows the reader to know what each character thinks and feels. By doing this, the reader is then linked to each character's thoughts, feelings, and actions. When the reader is invested in the characters, they actually care about the characters, making it feel like the reader is making choices with the characters. The Secret Garden's main themes are that home is where your heart lies, and being unselfish leads to happiness. Thus, by using the third-person omniscient viewpoint, the reader is connected to Mary and Colin, and their personal growth through the story deeply affects the reader. These children were sour, spoiled, and ungrateful at the beginning. Then, they meet Dickon, and he opens their entire world. Mary becomes full-of-life. She gains a healthy glow, her heart is warmed by him. When she introduces him to Colin, the same thing happens. We, as readers, share in this through the use of the third-person omniscient viewpoint.
