If you want to understanding something about how many of the women religious in these USA have gone completely off their rockers, here is the book to get.
I have the first book, from 1997. Now there is an updated, second version.
This book is now available for PRE-ORDER at a reduced price. Based on my reading of her first version, I’ll recommend this sight not-yet-seen. In the new book Carey drills into the “doctrinal assessment” and the LCWR, as well as the rise of new communities which are more traditional (read: not crazy).
