What to read after Run, Boy, Run?

Run, Boy, Run is the extraordinary account of one boy's survival of the Holocaust. Srulik is only eight years old when he finds himself all alone in the Warsaw ghetto. He escapes into the countryside where he spends the ensuing years hiding in the forest, dependent on the sympathies and generosity of the poor farmers in the surrounding area. Despite the seemingly insurmountable odds, several chases, captures, attempted executions, and even the loss of his arm, Srulik miraculously survives.
