According to the review:
"It will come as no surprise to anyone who has read any of Roscini’s previous work to hear that Cyber Operations and the Use of Force in International Law is a very well written book. It is engaging to read, focused and clear throughout. There are helpful touches, like the bullet point summaries at the end of each chapter listing the key points made therein, or the handy tables setting out the analysis in a different form for quick reference. As has been noted above, the book is extremely well researched and provides detailed analysis on virtually any question that one might raise on the application of the jus ad bellum or jus in bello to cyber warfare. Marco Roscini is now one of the leading legal experts in the world on cyber operations and Cyber Operations and the Use of Force in International Law forms one-third of a recent 'holy trinity' of major works on the topic. It is essential reading for anyone interested in cyber war and international law."
