During WW2 Ukraine was part of the Soviet Union and the main characters are captured there and are native to Ukraine.The Germans called people from Soviet Union "people of east" because they are in east or Russian even though they aren't.
If there is a topic about WW2 Germany is the obvious country in the war.In the book she is transferred to Germany (mostly likely West Germany because the UK and Americans are on her side of the country).Treatment is bad for her obviously because people who are non Aryans are inferior to the Germans.Then Germany is occupied by the allies and the Soviet Union.
The first place that our characters are in and live to work for awhile until it got bombed by the allies.It the place where the characters spend the most time in.
A place where you die or live.This is where Juli works and one day Lida got here to transport the wounded and saw doctors kill or treat the wounded.
A place the title is true Lida is making bombs for Hitler or at least Germany war effort.She now eats and live here with her roommates/friends.They put dirt instead of powder to sabotage so it could explode not to the allies but to the Germans instead.
a place where Lida and her friends are free from German oppression and Soviet execution.She gets better food and a place to sleep.She found out Larissa is alive at the camp by a letter at the end.
