Albert Camus was a French philosopher and author who gave rise to the idea known as absurdism, the idea that humans live in a meaningless, chaotic universe. His novel, The Stranger, reflects this idea quite well. The novel is about a man named Mersault who, after his mother's death, murders an Arabic man on a beach and is sentenced to death.
Throughout the novel, Mersault is quite passive to the things around him; to his mother's death, to him shooting the Arab, and to his death sentence. This suggests the idea of absurdism: why should he protest to what is happening when he will one day die? While I like the message and the ideas the book puts forward, the writing can be a big lackluster. For example, the first half of the the novel is quite boring and moves at a snail's pace, which made it hard for me to remain interested. Thankfully, the book is quite short so it's not that big of an issue. I would recommend this novel to fans of philosophy or like novels about existentialism.
