Heart of darkness

This book, 'Heart of darkness' was written by the British writer Joseph Conrad and published in 1902. Conrad wrote this novel from his own experience as a member in steamboat. 
The protagonist Charlie Marlow and his companions were along the River Thames, and he started talking about his experience as a steamboat captain on the River Congo. He saw a horrible situation there. One day, he heard that there was a great, important, brilliant agent named Kurtz. Marlow was getting interested in him, as he went, he knew something serious and weird...?
Honestly, I didn't get what this novel really wanted to say clearly. However, I think this novel includes the human's darkness. Though Marlow saw black people (natives) work so hard, he didn't do anything to make this situation better. He saw that, but he hid it somewhere deep in his heart. It seemed that this represented the human's darkness.
I didn't like reading this book actually because this book was to hard for me to read through and understand. In addition, the speed was a bit sluggish. Therefore, I don't recommend this book to my classmates. If there is anyone who is interested in European history, especially colonial period, I guess they can enjoy reading this!
