Heart of Darkness. by Joseph Conrad

Originally published serially as a three-part story, Heart of Darkness is a short but thematically complex novel exploring colonialism, humanity, and what constitutes a savage society. Set in the Congo in Central Africa, the tale is told in the frame of the recollections of one Charles Marlow, a captain of an ivory steamer. Marlow's search for the mysterious and powerful "first-class agent" Kurtz gives way to a nuanced and powerful commentary on the horrors of colonialism, called by some the most analyzed work at university-level instruction.
