I had to stop reading half way through this book, take a mosquito racket and zap myself with it just to remind myself I was alive. I have never been so irritatingly bored while reading a book as much as I was reading/listening to Heart of Darkness.
(In fairness, I was on a road trip listening to the audio book, and the narrator, Tom Franks is a huge reason why I had to stop the CD and sit in silence for another few hours just to get my ears to recover from listening to him.)
