Ms De Jong was present in London to see the annual prize presented and said she has finally been given “a story”.
She was hidden with a Christian foster family in the Netherlands before her birth parents were transported and murdered, and said that during the years of fear and persecution she had “no words”.
Van Es said: “There are two ways in which it could be a good book to have in the world. There’s a scary way in which antisemitism and extreme nationalism and conspiracy theories are around in a way that they weren’t 10 years ago. But also another way in which it is quite a healing book.”
Van Es and Ms De Jong have spoken of the power of stories and the need to give a voice to the silenced and the downtrodden, particularly to counteract “anti-Semitism and extreme nationalism”.
Ms De Jong, 85, said that during the war her life story could not begin under Nazi rule, and after the war cultural silence and the death of so many witnesses prevented any account of her experiences.
She felt she was not born until 1945, when her life could finally begin.
Ms De Jong has also credited Van Es – the grandson of the foster parents who cared for her – with telling that story to the world.
The Cut Out Girl charts her incredible survival in the occupied Netherlands, and also the moving process by which Van Es and Ms De Jong became friends.
Ms De Jong said: “I never thought I had a story that would be worth writing down. He wrote it down and it was a story. There was a story, but after the war nobody spoke about it, it was not an issue, not a subject. Nobody knew about this story before the war, nobody knew about this story during the war. After the war there was no story, nobody knew anyone who was living before the war.
“I was not born until after the war. I was alive, but my feeling was I just started after the war – before that time I had no words.”
Of the 140,000 Jews in the Netherlands before the war, about 70 per cent were murdered.
Ms De Jong said it was hard to speak about what happened with so few surviving witnesses to the persecution.
Her story has now been recognised by the literary establishment, with Van Es claiming the £30,000 annual prize for the Costa Book Of The Year Award.
Van Es, an Oxford academic, feels that giving life to the stories which have so long been silenced is an important way to remember and to heal old wounds.
He said: “I feel I have never known someone as well as I have known Lien. It just never happens, when you hear someone’s earliest memory. Lien had that incredible trust to say, ‘I give you my life’. I felt like I was watching her grow up. She felt younger than me. Lien was saying things about how important stories are to your identity. That thing she said about how she didn’t feel she existed before 1945.
“Without somebody to laugh and cry with you about a common story, that’s what it is to live. Without that you’re just a body.”
Chairing the panel of judges, news presenter Sophie Raworth hailed the work as “incredibly important”.
