Supremely gripping. Sands has produced something extraordinary. Written with novelistic skill, its prose effortlessly poised, its tone perfectly judged, his book teems with life, from the bustling streets of Habsburg Lviv to the high drama of the Nuremberg trials. One of the most gripping and powerful books imaginable

Important and engrossing. . . even when charting the complexities of law, Sands's writing has the intrigue, verve and material density of a first-rate thriller. . . He can magic whole histories of wartime heroism out of addresses eight decades old. Or, chasing the lead of a faded photograph, he can unearth possible alternate grandparents and illicit liaisons to be verified only by DNA tests. . . an exceptional memoir

Engrossing ... Sands has written a remarkable and enjoyable book, deftly weaving his own family history into a lively account of the travails of the early campaigners for international human rights law

A magnificent book. A work of great brilliance. There is narrative sweep and intellectual grip. Everything that happens is inevitable and yet comes as a surprise. I was moved to anger and to pity. In places I gasped, in places I wept. I wanted to reach the end. I couldn't wait to reach the end. And then when I got there I didn't want to be at the end

A fascinating and revealing book, for the things it explains: the origins of laws that changed our world, no less. It's also a readable book, and thoughtful, and compassionate. Most fundamentally, though, it's a book that tells a few individual human stories that lie behind the world-changing ones. That storytelling isn't redemptive - what could be, in this context? - but it confronts all those silences and challenges them. That challenge makes it an important book too

A vivid and readable contribution, part memoir, part documentary, to the history debate ... Much of the most compelling material in this book is personal ... Moving and powerful

Outstanding ... This is the best kind of intellectual history. Sands puts the ideas of Lemkin and Lauterpacht in context and shows how they still resonate today, influencing Tony Blair, David Cameron and Barack Obama. When we think of the atrocities committed by Slobodan Milosevic or Bashar al-Assad, it is the ideas of these two Jewish refugees we turn to. Sands shows us in a clear, astonishing story where they came from
