Query: Nothing about Congo

If you think that when you read this book you will know something about Congo you are wrong, this book explains electronics, volcanoes, weather, etc, about Congo you will read about 20 pages, the descriptions of all the procedures are really boring and if you are not on that field you will not understand, maybe it was a real story, may be not, I really think not.
