How would you respond to his memoir Elie Wiesel?

The mood is very gloomy throughout the book until gets to the point of total tragedy. Life at the concentration camp is horrible for the Jews. The prisoners are straving, being tortured, and are murdered often... They never know when they will be killed. Fear is always within' them. Most of the book takes place in the winter time, which makes the book even more gloomier. Even the title of the book, "Night", suggests darkness and emptiness.
