After her father's death in 2015, Norwegian-Israeli Monica Gorlen Fallon discovered a big collection of letters and documents he had saved. Most of the letters were written by her grandmother, Gertrud, to her son Heini, who travelled with a Kindertransport from Germany to Sweden in July 1939. An additional fourteen letters were from Heini's friend Walter Mayer. Monica translated these letters and compiled them into two books, My Heartchild and Dear Heini.My Heartchild is a selection of Gertrud's letters, written every second day. The letters reveal her love to her only son and her reactions to the life he described in Sweden. They give a close picture about life as a lonely Jewish woman in Hitler's Germany.
