Yeonmi Park said this quote

But as I began to write this book, I realised that without the whole truth my life would have no power, no real meaning. With the help of my mother, the memories of our lives in North Korea and China cane back to me like scenes from a forgotten nightmare. Some of the images reappeared with a terrible clarity; others were hazy, or scrambled like a deck of cards spilled on the floor. The process of writing has been the process of remembering, and of trying to make sense out of those memories.
