Explanation:

In literature, theme is the central idea, message or lesson that a literary work expresses about a topic, and which states something about life, principles or values that can be applied to our lives or to other literary works. Sometimes, this idea is directly stated in the text or story, but more commonly it is not, so it is up to the readers to find it out.

Examples of themes are "Everyone has dark secrets," "Love wins in the end", "It only takes seconds for fate to change" and "Nature often triumphs over man's quarrels."
