Danny,
From this fan review on "Goodreads," I gotta say both "no, but thanks for looking" along with that I will check this early Brunner novel out. I include a partial excerpt of the fan review. This site won't let me post the the link:
"...1990s Britain is on the verge of total collapse due to economic and ecological disasters around the world. A fascist government is on the verge of taking complete control.
Researcher Claudia Morris discovers disturbing patterns in children crimes and reporter David Levin senses a potential story. They soon discover that these kids aren't just simple juvenile delinquents but something more. Each of these kids possess a strange power of charm."
Wrong side of "the pond." But I really like Brunner, and that kind of "strange new bunch of kids" idea alway has some appeal for me. So you have given me a new book to search out and explore!
Meanwhile, thanks again for any efforts in finding my story set in Chicago, USA.
