now that the emotions have settled.... 
 Rose Under Fire is a fairly straightforward, linear book. You guess the "plot twist" (it feels gross calling it that but my sleepy brain cannot think of a better word) pretty easily, if you are familiar with WW2 fiction and non-fiction stories, you can anticipate the story, but then Elizabeth does something rarely seen in ww2 historical fiction novels. She goes through the After of the event with the characters. 
 Spoilers ahed: 
 There is a good amount of this book dedicated to the reality of PTSD with holocaust survivors, a topic that is either completely ignored or made very simple in most other young adult AND adult fiction. In particular, the scene of Rosa taking her test was so moving because it is something so small and seemingly insignificant that causes her to panic and recoil. This is something that otherwise, I may not have ever thought of as possibly triggering PTSD but now makes so much sense that it would. I think that alone is a reason to value this book but there are so many other reasons inside that mark this book as important and valuable.
