Included in this Definitive Edition are diary entries previously omitted from the original, passages which reinforce the fact that Anne was first and foremost a teenage girl, not a remote and flawless symbol. She fretted over her emerging sexuality; often found herself in disagreement with the adults around her; and veered between the carefree nature of a child and the full-fledged sorrow of an adult living under extraordinary conditions and unbearable strain. Anne emerges more triumphantly and heart-breakingly human, more vulnerable, and more vital than ever.

Anne Frank and her family hid in the back of an Amsterdam warehouse for two years in an effort to escape the horrors of Nazi occupation. Only thirteen when her family went into the Secret Annex, she reveals her daily life as the world around them succumbed to the worst horror the modern world had seen, facing hunger, the threat of discovery and death, estrangement from the outside world, and above all, the boredom, the petty misunderstandings, and the frustrations of living in such confined quarters.
