This is a brilliant synthesis of the history of half a century of transnational resistance and opposition networks in the Baltic Sea region . . . This monograph is well written, highly readable, and follows a convincing line of argumentation. The author is careful with terminology and his study is indeed a pioneering work. He uses the relevant historiography in English, Estonian, German, Polish, and Swedish, as well as archives in Estonia, Hungary, Poland, and Sweden. In addition, the contemporary press and fifteen interviews are employed to offer a broader perspective.
