Albert Camus tackles the idea of Nihilism, emphasising the absurdity of life within the pages, and give us a moral dilemma that will eat your brain in the end: "In front of the inevitable, does anything truly holds any meaning?". 

We watch the protagonist, Meursault, navigate this exact question through the book until the very end. I cannot explain more than this since it'll go on spoiler territory, but I 100% recommend you to give it a chance. 

And if you don't get the book the first time, take a break, and come back for a reread another time. You can read it in one sitting alone (I myself read it in three hours when I got it). This is one of those books people might not understand on a first sitting and that's totally fine!
