The Immoralist by Andre Gide

I'll admit it: I mostly bought this book because I loved the graphics on the cover--the purple woodgrain, the 50s-looking font, the yellow circle that seems to suggest a sun. I was also swept up in an early college years penchant for existential literature, and this seemed to fit snugly in with the likes of Camus and Sartre. But unlike classic works like The Stranger and No Exit, I can't remember a thing about this book.
