Query: Magnificent writing

The prose is tight, it's really wonderful. Vachss is really getting to be an outstanding writer, in a technical sense. He also is great at developing characters and making them really three dimensional. However - the "infomercial" part of this book was too much a part of the plot element - it took too much time and was very obviously a heartfelt pitch on a subject I also find compelling. But it got in the way of the story...Anyone who really likes any of Vachss books should really read Flood, the first book in the series and really the best in terms of depth of character. It's really remarkable.
