Definitely one of Albert Camus’ most famous novels, The Stranger is an amazing insight into humanity and the absurdness that surrounds us all. Don’t read this book at the beach. It’s best to be read in the dim light of your boarded room in the muggy nights of summer, wine nearby. It’s short enough to easily read twice, back-to-back, and I would recommend doing just that.
I would also recommend reading Camus’ L’Hôte first. The translation can be either ‘The Guest’ or ‘The Host’. It just depends on what you make of the story.
