Suspicion follows Iboja and her sister as they seek refuge in foreign lands, learn new languages and new songs, until they're flung in a train cart bound for a terrifying unknown. One of the Holocaust's last living witnesses, she recounts her brutal passage through the Nazi concentration camps. As a horrifying new normal takes hold - black smoke billowing up daily from the crematoria - she searches for fragments of hope in the resilience of her comrades, even in the disfigured hearts of her oppressors.
