By presenting the material in a straight-forward, lucid manner, he maximizes the impact without getting too graphic. The personal insights scattered throughout the book are of particular notice; by helping explain what he was thinking when these atrocities were occurring, it allows you to see things from his point of view, helping you understand what allowed this terrible situation to proceed in the manner in which it did and garnering quite a bit of empathy for others who may find themselves in the same situation. Hopefully, after reading this book, you will have a clear understanding of how these terrible things can happen, and more importantly, a clear understanding of how to keep them from happening in the future.
The bottom line: Simon Palmer has written an important, meaningful book. He is clearly writing directly from the heart and what he has to say will break yours. The guts it took to put this all down on paper is remarkable and his self-analysis pulls no punches. Throughout the course of the book, he shows a clear awareness of his issues and what needs to be done to counteract them; here's hoping that telling his story to the world will help him sort through them.
