**NAMED FINANCIAL TIMES "TOP 10 BOOKS OF THE YEAR"** **NAMED EVENING STANDARD "BOOK OF THE YEAR"** **NAMED NEW STATESMAN "BEST BOOK OF 2017"** A warm and intimate memoir by an acclaimed historian that explores the European struggles of the twentieth century through the lives, hopes, and dreams of a single family—his own. Uncovering their remarkable and moving stories, Mark Mazower recounts the sacrifices and silences that marked a generation and their descendants. It was a family which fate drove into the siege of Stalingrad, the Vilna ghetto, occupied Paris, and even into the ranks of the Wehrmacht. His British father was the lucky one, the son of Russian-Jewish emigrants who settled in London after escaping the Bolsheviks, civil war, and revolution. Max, the grandfather, had started out as a socialist and manned the barricades against Tsarist troops, never speaking a word about it afterwards. His wife Frouma came from a family ravaged by the Terror yet making their way in Soviet society despite it all.  In the centenary of the Russian Revolution, What You Did Not Tell revitalizes the history of a socialism erased from memory--humanistic, impassioned, and broad-ranging in its sympathies. But it is also an exploration of the unexpected happiness that may await history's losers, of the power of friendship and the love of place that made his father at home in an England that no longer exists.
