An author chooses everything about a book:

• where it is set
• what happens
• who the characters are
• what those characters are like

This is called authorial intent.

Authors also think hard about what they want their readers to feel when they are reading their books.

When someone reads a book and really likes it, they often read other books by the same author. This is because they enjoy how that author writes and how that author makes them feel.

For example: Lots of people enjoy reading Roald Dahl’s books because they know they’re usually funny, have interesting characters and will be written in a way that makes them feel happy.
