Three days later, her sister Danka joined her, where they forged an incredibly strong bond of love and compassion that would help them survive the three years and forty-one days that they would endure in the camp, undergoing hunger, torment and abuse.
During these years, Rena and her sister narrowly escaped Nazi experimentation, underwent forced labour and in January 1945, the death march to the Ravensbrück concentration camp.
Their parents are believed to have been murdered in Auschwitz and their sister Zosia's fate and her children's is still unknown.
Partnered with writer Heather Dune Macadam, Rena told her moving story of surviving the German Nazi concentration camps with her younger sister Danka.
[See footnotes to Kindle edition of Rena's Promise] Her sister, Danka, died November 21, 2012.
