Really appreciate all the work and time people who work on this book put into documenting and sharing us these important stories. Unfortunately, due to the nature of the subject matter, the book can't really go into full details of each case, but this should be enough as a starting point.
Since the story of each case is written by different authors, the quality of each chapter varies. Some feels like it doesn't say anything at all or will just leave you confuse unless you've followed the case through social networks when it started.
One word of warning, though; reading this might make you feel hopeless so make sure that you have enough mental energy to deal with that.
