These stories and essays are well-crafted, yet easy to read. There are lessons to be learned from each piece, and these lessons can be identified easily. But the themes and ideas remain in your head and leave you thinking long after you set the book down - thinking about Anne Frank's life in the Nazi-occupied Europe as well as her ideals. Anyone will discover some aspect of their persona mirrored in Frank's characters, whether it may be through Paula or Kathy or Eve or anyone else.
You should approach the book with an open mind and respect for the writing. If you see that Frank was an intelligent young human being, and not a little kid whose writing you can deal with condescendingly, read this book. Otherwise, skip it. This is honest, wise, well-crafted work, and it should be treated as such.
