I've read several books on homelessness, particularly from a religious/Christian perspective, in preparation for an upcoming work event. This had a different and interesting take on the issue from the others I've read. Rather than addressing statistics (although those are in there) or the standard types of responses, she takes it deeper and strongly encourages advocacy and empowerment.
I had some quibble--as I often do in books that try to do this--of her propositions early in the book that cast all Christian organizational/congregational approaches in one light. Really, there are lots of congregations that have been involved in these issues since their beginnings hundreds of years ago, and many of them do not have the same overtly patronizing or dismissive approach to those they serve as the organization she used. Many of them are quite empowering and are engaged in advocacy as well. She studied one large gospel-mission organization and made sweeping generalizations based on that, which is problematic. It would have been nice had she taken the time to find a better cross-section of organizations to compare approaches.
On the other hand, I do agree with her end conclusions--that we need be more engaged in advocacy on root causes rather than addressing only an individually-based approach of "here's how you can live your life better." Towards the end of the book she gives several examples of organizations and congregations who have done exactly what she's talking about (which is interesting, given her earlier assertions, seemingly, that few are doing these things). I enjoyed reading those examples and will be doing some web-searching to learn more about some she mentions.
Overall, I will definitely be recommending this book and using it myself for background in preparation for the event. It will generate lively discussion!
