Sailing up the Congo River in search of the enigmatic trader Kurtz, Captain Marlow enters a world where civilization's veneer gives way to savagery and greed. Along the journey he witnesses both the vast beauty of the African wilderness and the brutal horrors of imperial exploitation. Joseph Conrad's haunting novella is more than an adventure tale - it is a searing exploration of colonialism, moral corruption, and the fragile boundary between light and darkness within the human soul. First published in 1899, Heart of Darkness remains one of the most unsettling and enduring works of modern literature.
