Hetty's family was torn apart following the German invasion of the Netherlands. Rounded up by the Nazis and then separated from their parents, Hetty and her brothers were sent to the Children's House, within Belsen concentration camp. As one of the eldest, Hetty became the 'Little Mother', helping to care for not only her siblings, but the other children as well.

In a direct and powerful style, Hetty recalls one of the remarkable, largely untold stories of the Holocaust - the extraordinary struggle and survival of this group of children through those terrible years.
