Demian by Hermann Hesse

Emil Sinclair, is a young man torn between his strict moral upbringing, and the darker, more tempting tone of his own desires.
When he meets Max Demian, a classmate who introduces him to new ideas that challenge conventional notions of good and evil, he struggles, and seeks guidance from various figures, including a musician named Pistorius and Demian’s mother, Frau Eva. His search takes him on a journey of self-realization, as he learns to embrace the duality of his nature, both divine and dark. The novel culminates during World War I, where a final encounter with Demian leads Sinclair to the ultimate understanding, that true guidance and self-knowledge must come from within.
