Like others, I found the book useful, particularly for case studies and as a general introduction. I was unimpressed by the rather vague characterization of the differences between mainstream schools of thought (military, religious etc.) and cults as the Authors identify them - I'm left with the idea that she's particularly concerned with not attacking deeply rooted beliefs and patriotic feelings, but the analysis of the difference - if there really IS a difference - is largely unconvincing. It is important to notice that the treatment of Large Group Awareness Training (LGAT) programs is incomplete in the paperback edition, due to a pending cause with Landmark Education. All references to the widespread (and wealthy enough to stop just about anyone) Landmark Forum have been removed. So if you want her description and analysis of it, you'll need to get the hardback edition.
