‘Ariana Neumann’s story may strike a chord, and rightly so. The slow and pitiless brutality that took hold of much of Europe in the 1930s is a story that can never be told too often. What makes this account so effective is that it’s personal and, because of the dogged extensiveness of her research, Neumann reminds us of the small details that make the Nazi persecution of the Jews all the more chilling. It’s not always a grim story. Alongside anger and despair there is love and hope. But the message is stark. This is the way bullies work. When Time Stopped is more than just history. It’s a warning.’

– Michael Palin

‘When Time Stopped is Ariana Neumann’s journey of discovery, lyrically set down in this truly exceptional book. She shines an intimate light upon a time unique in its horror, and tells a story of bravery, and rare survival. Yet the events she describes happened more than two decades before she was born. To a man to whom she was very close, but whose secrets she was only able to pursue after his death - thanks to the one hoard of evidence he never destroyed. This is a work of very great talent.’

– Jon Snow, journalist and Channel 4 television presenter.

‘Grippingly readable, chillingly sad but above all deeply sympathetic and suffused with love and understanding throughout. A compelling and humane portrait of Ariana Neumann’s father and his courageous decision to survive.’

– Anne Sebba, bestselling biographer and historian

‘When Time Stopped is a remarkable and beautifully written book. Hans Neumann's story is astonishing, confirming that when it comes to the Holocaust we should expect only the unexpected. This is one of the most powerful and profoundly moving family stories of the Holocaust to have been published in many years and a must read.’

– Professor Dan Stone, Professor of Modern History and Director, Holocaust Research Institute, Royal Holloway, University of London

‘Absolutely remarkable’

– Edmund de Waal

‘When Time Stopped is an astonishing family memoir that will imprint itself on your psyche as only the best books can, forever changing the way you look at your own family. With a mastery of the dogged art of research rarely seen, and with an exquisite narrative sensibility to match, Ariana Neumann has breached the hidden surface of her family’s tumultuous past and brought not only their tragedies and sorrows, but also their joys and loves, to indelible light. I will carry the experience of this book with me for a very long time.’

– John Burnham Schwartz, author of The Red Daughter, Reservation Road and The Commoner

‘In a grand house in Caracas in the 1970s, a young girl comes of age dreaming of becoming a detective and solving mysteries, particularly the mystery of her charismatic, enigmatic father. Four decades later, after he dies, and herself a mother, she embarks on an extraordinary journey through Central Europe and South America to uncover her father's past. Through pre-war Prague's intelligentsia to the rise of fascism in Europe to the horror of Hitler's camps, she combines a daughter's love with a profound yearning for truth. The result is a love letter to a father who, out of sheer will and determination, did not allow the Nazis to destroy him - and who rose to become one of Venezuela's most successful industrialists. Part literary memoir, part mystery tale, Ariana Neumann's tribute to her father is a classic story of redemption and love.’

– Janine di Giovanni, 2019 Guggenheim Fellow and author of The Morning They Came for Us: Dispatches from Syria

‘This book is utterly riveting: Ms. Neumann's memoir reads like a detective novel, as she unravels her late father's complex, agonizing yet inspiring trajectory. Conjuring the lives of her relatives murdered in the Holocaust, she brings their lost world to vivid life.’

– Claire Messud, New York Times bestselling author of The Emperor’s Children and The Woman Upstairs

‘I’ve read countless memoirs. I’ve read hundreds of books about the Holocaust and mysteries and detective stories and rigorously researched tomes of history and psychological studies of the effects of trauma. But never in my reading life have I ever come across anything akin to this magical, brilliant and gripping work of art combining all of these elements into a lyrical tapestry of one woman’s quest to understand her father’s mysterious past and therefore her own. To call this moving is an understatement. It is a journey of untold grace, sorrow and love.’

– Deborah Copaken, bestselling author of Shutterbabe: Adventures in Love and War and The Red Book

‘Growing up in a comfortable Caracas home, surrounded by joy, gaiety and the ‘birds of paradise’ -- and a father so revered that he had streets named after him in Venezuela -- Ariana Neumann willed an adventure to come her way. But nothing could have prepared her for the true-life story which was to unfold upon her beloved father’s death, back into the darkest depths of human history.

Lucidly-written, this is a gripping, heart-wrenching journey back to wartime Prague and Berlin. Ariana Neumann has written the book that her remarkable father simply couldn’t.’

– Tom Gross, former Prague and Jerusalem correspondent, Sunday Telegraph

‘Remarkable...Through painstaking, meticulous research Neumann tells the true story-part memoir, part history-of her heart-wrenching and ultimately life-affirming journey in uncovering her family's long hidden past.’

– Georgia Hunter, New York Times bestselling author of We Were the Lucky Ones

‘Ariana Neumann's beautiful, meticulously researched memoir is an extraordinarily moving story of a family’s lost history, a father’s well-kept secret, and a daughter who pieces it all together with courage, tenacity, and most of all, love.’

– Dani Shapiro

‘When Time Stopped is a beautifully told story of personal discovery, of almost unimaginable human bravery and sacrifice, and a harrowing portrait of living, dying and surviving under the yoke of Nazism.’

– John Le Carre

'The story Neumann uncovers is worthy of fiction with hairpin plot twists, daredevil acts of love and unexpected moments of humor in dark times. Given the slew of colorful characters and dramatic details, she could have turned her painstaking research into a historical novel. Instead she has written a superb family memoir that unfolds its poignant power on multiple levels. Yes, her account of one Jewish-Czech family’s race to outwit the Nazis makes for thrilling reading. But just as important is her lucid investigation of the nature of memory, identity and remembrance.'

– The New York Times Book Review

– Tom Gross, former Prague and Jerusalem correspondent, Sunday Telegraph

‘Neumann’s efforts to tell [her father] Hans’s story chronologically, rather than in the order she unravelled the mystery, is especially effective. At times the revelations are so extraordinary to modern eyes that the memoir has an almost fictional feel.’
