A collection of previously unpublished letters from the American cult icon on the art of writing. Charles Bukowski was one of our most iconoclastic, raw, and captivating writers, whose stories, poems, and novels have left a lasting impression on our culture. "On Writing" gathers Bukowski's thoughts and reflections on the craft to which he dedicated his life. Penetrating, unsentimental, and often humorous, "On Writing" is filled not only with memorable lines but also with the author's characteristic toughness, tempered by moments of grace, pathos, and intimacy. In the unpublished letters collected here, addressed to editors, friends, and colleagues, Bukowski expresses himself brutally openly about the struggles of the work and remains uncompromising when it comes to the absurdities of life and art.
