Heart of Darkness from first glance

At first glance, Heart of Darkness by Joseph Conrad seems like an exciting novel about a man on a dangerous adventure in Africa. Along the way he supposedly only finds his "dark and evil soul." The only books I usually care for are stories like these where the protagonist goes on an adventure and discovers something great. Hopefully this story will live up to those expectations. I am very excited to get started and find out what he will find.
