I've got an oral task coming up soon about existentialism. I need some related texts! Does anyone know any (not the generic ones such as Stranger by A. Camus)?
If you *really* wanted to go out of the mainstream, you could try Osamu Dazai's No Longer Human, which is interestingly quite similar to Camus' L'Etranger.
I'm going to have to go with Metamorphosis as well. But it does depend on the branch of existential literature you want to explore. As in, you could do Kafka's "Metamorphosis" but you could equally do Walt Whitman's "Song of Myself"; both have heavily existential themes that you could talk about. For something more contemporary, I'd recommend Tim Winton's novel "Breath" - it's a great read!
