In 1940, about eighteen thousand Jews lived in The Hague. Among them are six-year-old Lyn and her parents, and numerous uncles, aunts, cousins. When in 1942 it became obvious what the Nazi occupation was threatening to the Jews, the parents tried to save their daughter. So Lin ended up in a foster family, the first of a series of families, houses, secret shelters that she had to change over three years. Thanks to ordinary people who secretly helped Jewish children in the Netherlands during World War II, Lin survived the Holocaust. After her release, she returned to her first foster family, the van Es family. Bart van Es, a British philologist and professor at Oxford, always knew that his grandparents sheltered a Jewish girl during the war, who they raised as their child. Lin was part of his family, but some event in the past severed all ties. He sets off on a journey across the Netherlands to find Lyn so he can learn and tell her story. The documentary research became a deeply personal experience for the author. The book was awarded the British Costa Prize in 2018. The publisher's design is preserved in PDF A4 format.
