Precious few books or articles do justice to both the core challenges facing Ukrainian foreign policy and the reasons Ukraine's success or failure in meeting them matters to the rest of Europe. Garnett's book does. He brings balance and subtlety to the core issue -- Ukraine's relationship with Russia -- treating specific conflicts in detail, but only after laying out the deeper and more basic factors at work. Rather than end at that, he goes on to explore Ukraine's relations with its remaining neighbors and to show in what fashion Ukraine will, amid this larger mosaic and despite the studied underestimation of the West, figure in the well-being and safety of the rest of the continent.
