East West Street [suggested by Ross Allatt]

When he receives an invitation to deliver a lecture in the Ukrainian city of Lviv, international lawyer Philippe Sands begins a journey on the trail of his family’s secret history. In doing so, he uncovers an astonishing series of coincidences that lead him halfway across the world, to the origins of international law at the Nuremberg trial. Interweaving the stories of the two Nuremberg prosecutors (Hersch Lauterpacht and Rafael Lemkin) who invented the crimes or genocide and crimes against humanity, the Nazi governor responsible for the murder of thousands in and around Lviv (Hans Frank), and incredible acts of wartime bravery, EAST WEST STREET is an unforgettable blend of memoir and historical detective story, and a powerful meditation on the way memory, crime and guilt leave scars across generations.

All That Man Is

Nine men. Each of them at a different stage of life, each of them away from home, and each of them striving — in the suburbs of Prague, beside a Belgian motorway, in a cheap Cypriot hotel — to understand just what it means to be alive, here and now.
Tracing an arc from the spring of youth to the winter of old age, All That Man Is brings these separate lives together to show us men as they are — ludicrous and inarticulate, shocking and despicable; vital, pitiable, hilarious, and full of heartfelt longing. And as the years chase them down, the stakes become bewilderingly high in this piercing portrayal of 21st-century manhood. [Product description from Amazon]
