When Bad Things Happen To Good People by Rabbi Harold S. Kushner

Rarely does a book come along that tackles a perennially difficult human issue with such clarity and intelligence. Harold Kushner, a Rabbi facing his own child's fatal illness, deftly guides us through the inadequacies of the traditional answers to the problem of evil, then provides a uniquely practical and compassionate answer that has appealed to millions of readers across all religious creeds. Remarkable for its intensely relevant real-life examples and its fluid prose, this book cannot go unread by anyone who has ever been troubled by the question, "Why me?"

And on Wikipedia, you find:
Kushner rejects suggestions that human suffering is God’s punishment for misdeeds. He also does not believe that suffering is God’s way of teaching people valuable lessons about humility and spiritual strength. Rather, he believes that human suffering is an innate part of God’s creation of the universe and that its objects are selected at random. People do not fall ill or suffer tragedy because God chose to inflict it on them, he argues, but rather because this is the way of world. When the wheel turns one way or another, people are caught up in it—good people or bad people, but not because they are good or bad.
