Although I have not read this book, this story brings tears to my eyes. I have a cousin (genius) who suffers from paranoid schizophrenia. We were childhood companions. I saw the author being interviewed. For those who quickly dismiss the homeless as being lazy, and even enjoying their state of affairs, I say shame on you! I am sure there are pleny of lushes out there, but please do not judge a book by it's cover. Especially if you contend being Christian. Not everyone can "lift themselves up from their bootstraps". The valiant words of a healthy politician, who later died form Alzhiemers.
