What worked: This story covers a time right after the end of WWII. I didn't know much of what happened after the Allies, including the Soviets, drew up occupation zones. Readers find out what happened when the Soviets kidnapped young people that fit a profile. Mostly these were survivors of the war that fought against the Nazis and worked in the underground helping Jews.
Krystia and Maria's plight is based on factual truths. Readers also learn about the Werewolf Nazi group of young girls who were recruited to kill Allie forces in their attempt to reinstate the Nazis into power. Sophie's character is fleshed out and not just the one-dimensional evil Nazi youth. The girls try to help each other survive in the interogration camp, even when the anger they feel for Sophie is justified. I really liked this. Readers see that the war had shades of gray. That some people resorted to things to survive that they might have not have done otherwise.
There's a map at the back of the book which includes the occupation zones and where the girls had been held. Also there are facts which include why the Soviets singled out youth like the sisters and how the girls, with the help of some locals, were able to escape.
Powerful, heart-wrenching historical that takes place right after WWII. Heart-pounding action as the sisters learn that they need to rely on each other in order to survive being held by Soviet troops. A very satisfying addition to other Scholastic books in the Making Bombs for Hitler trilogy.
