I got a copy of Unchosen: The Hidden Lives of Hasidic Rebels after I saw it on a blog.
Since then, I have lent it to tens of people, and its circulating around. Its part of my library of books which I lend around. This one is in high demand, so I don't really know when it will get back to me. I really don't understand why most of those who rebel don't choose Modern Orthodoxy, but one day maybe I will understand.
Meanwhile there is an interesting post on FailedMessiah about the phenomenon.
