In 1941, 12-year-old Rivka Rosenfeld lives in the Warsaw Ghetto with her grandfather and two sisters in a synagogue because housing is scarce. When German soldiers slash her grandfather's beard, Rivka is compelled to write in between the pages of a library book by Hans Christian Andersen. Dr. Emanuel Ringelblum, founder of the Underground Archive--a compilation of Warsaw Ghetto experiences, asks her to contribute her stories to the archives and Rivka agrees, imagining her words rising up from the ground on wings of their own.
