It's been years since the Nazis invaded Max Rosen's home country of Poland. All the Jewish people, including Max's fam-ily, have been forced to live in a ghetto. At least Max and his sister, Zena, had Papa with them . . . until two months ago, when the Nazis took him away. Now Max and Zena are on their own. One day, with barely enough food to survive, the siblings make a dar-ing escape from Nazi soldiers into the nearby forest. They are found by Jewish resistance fighters, who take them to a safe camp. But soon, grenades are falling all around them. Can Max and Zena survive the fallout of the Nazi invasion?
