What is a theme of a book?

Question

if you know can you tell me the theme of the book Night by Elie Wiesel??

Answer 1

A theme is a unifying or dominant idea.

The major theme of the book is the horror that results from extreme prejudice. Because Hitler hated Jewish people, he caused them to be imprisoned, tortured, and murdered. The book records the horrendous experiences of Elie Wiesel, the Jewish author, during Hitler's reign of terror. He is arrested, imprisoned in a concentration camp, and tortured. Although he escapes death, he is totally devastated by the things he must endure and witness during the holocaust. The book is a recording of man's inhumanity to man at its worst.

Answer 2

The theme is the main story line of the book.
