Markus and Amalie Zack, Hanna's parents, were deported from Cologne, Germany, on October 30, 1941, to the ghetto in Lodz, Poland, and ultimately gassed in nearby Chelmno death camp on May 3, 1942. After reading the story in her book A Garland for Ashes (Meine Krone in der Asche in German), the Chemin Neuf Community invited Hanna to Lodz in July 2016 to testify to Christ's power to heal and transform.
