One common theme is social inequality. Novels often show different groups in society being separated based on wealth, status, or power. For example, in many classic novels, the rich live in a different world compared to the poor.
Unrequited love also frequently appears. Sometimes, one of the lovers may be more committed or have stronger feelings than the other. In 'The Great Gatsby', Daisy doesn't fully reciprocate Gatsby's intense love. Her hesitation and lack of complete commitment contribute to the tragic nature of their relationship.
A common theme is abandonment. Characters in these novels often feel deserted, whether it's by society, loved ones, or fate. Another theme is struggle. They have to fight to survive or find their place again.
Family is a very common theme. For example, in 'The God of Small Things', family relationships are at the core of the story, with secrets and love within the family being explored.
One common theme is coming - of - age. It often involves a young character growing up, facing challenges, and learning about themselves and the world. For example, in 'To Kill a Mockingbird', Scout Finch comes to understand the complexity of human nature and the importance of justice as she grows up in a racially divided town.
Family and redemption are often seen as well. The baby becomes a catalyst for the billionaire to re - evaluate his life and relationships. He may have had a difficult relationship with his own family in the past, and through the process of getting to know his own child, he heals and becomes a better person. The family that forms around the baby, including the relationship between the mother and the billionaire, is central to the story's resolution.
One common theme could be friendship. Many stories often feature characters who form strong bonds with one another and support each other through difficulties. Another theme is probably courage. Characters usually need to be brave to face the challenges in the stories, whether it's fighting a monster or standing up for what is right.
Isolation could also be a theme. The lost puppy was all alone in the big city, just as the artist was alone in his unappreciated world. They were both isolated in different ways, which added to the sadness of their stories.
There are several common themes. For instance, virtual reality. Novels often depict a world where people can enter a virtual world and what the implications of that are. Also, the idea of a universal language or communication system in a future where different species need to interact. And environmental collapse is a theme too, showing a future where the Earth's environment has been so damaged that it's a struggle to survive.
