I'm not entirely sure as I haven't read the novel in great detail, but the protagonist must be an important character. They are the ones having the experience of living in the bush of ghosts.
One main theme could be the exploration of the supernatural. The 'ghosts' in the title suggest that there's a focus on elements that are beyond the normal, physical world. It might also deal with survival, as living 'in the bush' implies facing the challenges of a natural and perhaps unforgiving environment.
In this novel, the protagonist is key. But we can't forget about the secondary characters like the kind neighbor who offers help when needed. And there could be a teacher or a role model in the story who imparts wisdom and knowledge to the protagonist, shaping their character and future actions.
The main character is Zucchini. He is a young boy who has his own story of loss and growth. Then there are his friends like Simon. Simon has his own quirks and personality that add to the group dynamic. Also, the adults in the story, like the kind caretaker, play crucial roles in the children's lives.
Obviously, the dog itself is the most important character. It's the protagonist whose life the story is centered around.
Often, there will be a love interest. This character will have a major impact on the protagonist's life, influencing their decisions and emotions. They may be a source of both joy and heartbreak in the first half of the protagonist's life.
The protagonist who is reincarnated as the villainess is very important. Also, the prince is a significant character as he is one of the main love interests in the story. Then there's the heroine of the original game who also plays a role in how the story unfolds.
The narrator, Mark Twain himself (in a semi - autobiographical sense), is of course very important. He takes us on his journey of discovery along the river.
The protagonist is at the center of the story in 'the life changer novel'. This character's actions and decisions drive the plot forward. Then there are the supporting characters. For instance, a teacher who imparts valuable knowledge and wisdom to the protagonist, which aids in their development. There might be a love interest as well. This character can add an emotional dimension to the protagonist's journey of change, either by being a positive influence or a source of conflict.
There might be an older, wise character, perhaps a community elder. This person could hold the key to a lot of the local knowledge and stories. And there could be a female character who is fighting for equality in a male - dominated society in Mississippi. She could be a symbol of change and progress within the community.
The protagonist is surely an important character. He is the one whose sporting life we are following. His experiences, dreams, and setbacks form the core of the story.
