I listened to this story of the search for Dr. David Livingstone via audiobook, and I often had the urge to just take in the entire book in one go. Yes, it was that awesome.
Livingstone, a British missionary who had lived in Africa for years, was asked by his government in the 1860s to solve one final geographical mystery: the source of the Nile. When he disappeared into the hostile and forbidding terrain, an American reporter, Henry Morton Stanley, was sent in to find him. During the search, Stanley sent regular reports that were printed in the New York Herald, like a serialized novel. American and British readers drank it up- couldn't get enough of it, apparently.
