<human>:  Who is the narrator of Joseph Heller’s novel, ‘Catch-22’?
<bot>: The narrator of Catch-22 is a character called Yossarian. Yossarian is a pilot who is trying to avoid being shot down by the enemy, but he is also trying to avoid getting a mental disorder called combat fatigue. The book is written in the first person, so the reader is inside Yossarian’s head. The reader knows what Yossarian is thinking, but does not know what other characters are thinking. The book is set during World War II, and is a satire about the absurdity of war.
