A Night Divided Beginning

Yesterday we started to read A Night Divided. The main character is a girl living in East Berlin during the Cold War. Her name is Gerta. So far, the story is telling about the first four years after the wall went up. The night the wall went up, Gerta's father and brother were on the other side of the wall, looking for work, and later, they planned for the rest of the family to join them. Now, the family is separated by the wall. I think that the problem in the book might be that Gerta and her mom and brother try to find a way to get over the wall to join her father on the American side of Berlin. I am excited to see what will happen in the rest of the book.
