The award-winning Canadian-Czech singer and composer Lenka Lichtenberg was going through her mother's effects in 2016 in Prague when she made a startling discovery. She found two small notebooks that belonged to her artist grandmother, Anna Hana Friesova (1901-1987). Inside each notebook, small enough to fit into a back pocket, were poems written while she was imprisoned in the Terazin (Theresienstadt) concentration camp during WWII.
