This is a big book and it needs to be, because it has both breadth and depth. The breadth comes from the geographical coverage. It doesn't cover only the obvious places, such as Nigeria: it also details the activities of the oil and gas industry in places that I didn't know had any! The depth comes from the explanation of the industry's structure, which includes not only the large corporations.
The text provides a survey of Africa's relationship to the international industry including both the activities in Africa of companies from abroad (notably now the Chinese) and those of African companies operating beyond Africa.
For me the most interesting parts are the accounts of the minnows - the small, entrepreneurial companies that one usually hears very little of - and of Africa's indigenous oil industry.
This is a serious-minded book that is concerned to inform and explain, though the author's strong emotional engagement with the continent also comes through.
