Fresh Air's story about journalist Lutz Kleveman's book about the battle over oil reserves in the Caspian Sea?

His new book is The New Great Game. The book is about the battle over the world's largest reserve of untapped oil and gas resources, located in the Caspian Sea and surrounding Central Asian republics. The oil alone is said to be worth $4 trillion. Kleveman claims that the United States, China, Russia and Iran are now engaged in a power struggle for control of the region's vast reserves and pipeline routes. Lutz Kleveman was born in Germany and studied at the London School of Economics. He has reported from war zones in the Balkans, Asia and the Middle East for the Daily Telegraph, Newsweek, CNN, The Independent, Der Spiegel and Die Zeit.
