Everyone who I have ever shown this book to has had a deep reaction to it. I wouldn't handicap this book by calling it a photography book alone, although the photos are very powerful and prominent, but the text deserves recognition as well. Plenty of personal stories of how people made this decaying city their home. Both epic and intimate. A testament of the human animal's ability to adapt and thrive. Thank god the authors got in to Kowloon before its destruction to create this book.
Also, as a side note: Any artist wanting reference material for decaying urban sprawl, look no further. This book makes for great city or science fiction reference, with unbelievable details (electrical boxes, pipes, hallways, stairwells, etc...)
