Unlike seemingly every other reviewer, I -didn't- enjoy the first part of the book; most of it is a collection of unsourced and unlikely atrocity stories. A couple of Google searches convinced me at least some of these were cribbed from weird extremist propaganda publications, or that the authors and these publications (and seemingly nobody else on the planet!) have used the same sources.
The cannibal micro-bios that make up the main body of the book are better, but nothing you won't find on Wikipedia and/or the major True Crime websites.
Overall, a complete waste of paper.
