"Fires in the dark" by Louise Doughty
I enjoyed this author's "Stone cradle", a story of Romani in the United Kingdom, so much that I determined to read others if I could find them.
This is the one I found, dealing with the lives of East European Romani from 1927 to 1945.You will be aware of what happened in Europe over that period.
Emil, whose secret name is Yenko, is one of the main protagonists. We follow him while his group is on their travels, in winter settlements, cherry harvesting and other things, watching as life and travel become much more difficult for them as a result of increasing government burocracy, new travel papers etc, all of this being aimed at making it easier to keep track of the Romani and to control them.
We read of invasions, battles, conquest by the Nazi armies, and eventual round-ups of the Romani groups, followed by transportation to concentration camps.
Emil escapes, following urging by his mother, and makes his way to Prague where he lives out the war, working on the black market as the only method available to him to keep safe and make a living. Near the end of the war he goes back to the camp to see if any of his family have survived.
This is a brief summary of a harrowing, and yet hopeful, story. There is plenty of incident, personality clash, humour and horror. I was surprised to learn that, per head of population, more Romani died under the Nazis than Jews, horrifying as the Jewish experience was.
I recommend that you read this book. No matter how good a person you are, I think you will be an uplifted and even better person as a result.
