A theme is the underlying message or idea that the author is trying to convey through the story. It's not explicitly stated, but rather emerges from the characters, plot, and setting.
Here are some examples of common themes in literature:
* Love and loss
* Good vs. evil
* The power of hope
* The importance of family
* The consequences of choices
* The search for identity
Understanding the themes of a story can help you to better appreciate the author's message and to connect with the characters on a deeper level.
