Clear, well documented, engagingly written and consistently arranged according to topic, this book has an added merit of no little value when compared to most literature on economical subjects: thanks to its conceptual clarity and the precise information that is transmitted to the reader, it can be read and understood with ease. A book defi ning Che s thoughts on economy was sorely needed. Most of those written in the past have done nothing to place his ideas in their historical context, including all of his radical shifts from 1959 to 1966- regarding the USSR and his own Cuba. Moreover, most of the concepts in these earlier books were buried under the weight of an enormous mound of information, making it impossible to follow the thin, red, revolutionary and internationalist thread that runs through Che s political and economical thoughts. Here that red line can be traced. A concluding chapter is dedicated to the political and cultural relations that Guevara had with other leftist movements. The fi nal bibliography, dedicated exclusively to the theme of research, is also excellent. -Roberto Massari in Che Guevara.
