In Nobel laureate Elie Wiesel's memoir Night, a scholarly, pious teenager is wracked with guilt at having survived the horror of the Holocaust and the genocidal campaign that consumed his family. His memories of the nightmare world of the death camps present him with an intolerable question: how can the God he once so fervently believed in have allowed these monstrous events to occur? There are no easy answers in this harrowing book, which probes life's essential riddles with the lucid anguish only great literature achieves. It marks the crucial first step in Wiesel's lifelong project to bear witness for those who died.

My take
Extremely powerful and moving.  Everytime I read it, it breaks my heart.  Wiesel does not hold back on his account of his time at Auschwitz, Buna and Buchenwald.  A tragic story.
