Kelly has a nice, straightforward way of writing, however you will not find any beautiful turns of phrase or lyrical passages in the writing. It was an easy and a quick read. 
 If you are looking for enlightenment or understanding of motivations or personal aftermaths of the characters, you will not find it in this book. The writing is all about the narrative. And while the atrocities of the concentration camps are visited here, the author treats them with a soft touch, never lingering too long or going into too much detail. 
 I enjoyed the characters though they were a bit two dimensional. Kasia's story was probably the most interesting, most likely because she had more support characters in her story which helped to add more to her background. 
 I was surprised to find out, in the author's note at the end of the book, that the three main characters are based on real people and the concentration camp, Ravensbruck, was also real. I would like to read more on the camp, as it was the only major camp exclusively for women.
