This is an outstanding book that, despite the heavy and somewhat depressing content, keeps you reading and never fails to shock.
Tracing the history of 'genocide' through a number of case studies, Power elucidates both the unique cause of each incident, as well as linking them to Western (read: American) (non)intervention. Overall, she offers a damning indictment of a failing international system.
A particularly interesting and engaging element is her appreciation of the work of Raphael Lemkin, who was the man behind the word 'genocide', and largely responsible for having it put on the global agenda. Her attention given to fairly representing what this man gave in the name of protecting the rights of those persecuted is appropriate, moving, and fairly unique amongst books of this genre. Ultimately, Power shows Lemkin's efforts to become a farce of international (in)action: reluctance to use the word when it suits, cynical use when it suits.
