28 Days by David Safier

28 Days follows sixteen-year-old Mira who smuggles food into the Warsaw ghetto to keep her family safe in 1942. When the ghetto is set to be liquidated, she is determined to find a way to keep her family safe. She meets a group of young people like herself who are planning an uprising against the occupying forces. She joins them, and they resist for 28 days, much longer than they thought possible.
