I'm a huge fan of Hermann Hesse. Beneath the Wheel is probably my favorite novel of his, although Steppenwolf & Demian are also fantastic. The Fairytales of Hermann Hesse
re-read every couple years. I've also bought it probably 5 times now, each time lending (giving?) it out to a friend. His fairytales hit the same themes as his novels and often do so with a bit stronger punch and a fun sense of magic.
