I love reading books about ballet! This is a beautiful story of two people one a boy who lived through the Holocaust and the other a young girl whose mother dies suddenly. 
I feel like this book was written in a way that makes the reader feel for both of these characters from the very beginning and when the perspectives start to converge it is done so that their stories still feel true to each of the characters. 
I loved reading about Katya and how she came to be a dancer. Katya believes that without dance she could not live and that is the driving force behind all of Katya's decisions throughout the book. 
John is trying to distance himself from the things that he did to survive the Holocaust and who he is becoming because of that experience. 
I loved each of these characters and how flawed they were. I will definitely be checking out more of this author's work.
