'This is a concise and nuanced overview of International Humanitarian Law (IHL). The structure is unusual. While the book reflects the state of the law with accuracy and sobriety, it nevertheless shows the idealist and philosophical ambitions of the authors. Legal issues are often discussed within a wider moral and ethical context. The authors add many basics on human rights and the enforcement of international law, which are not directly relevant for IHL, but ensure the reader understands the wider picture.'--Marco Sassoli, University of Geneva, Switzerland
