Another really good book. The book follows the "series of vignettes" style of the last book, but with more of a serialized tone instead of an episodic one.
There are a few things I'm wondering though, which might not be answered in future books - in particular, what City was Interstellar Master Traders supposed to be, exactly? Florence? Rome? Jerusalem? Goodness knows that last one would have some serious Unfortunate Implications if that was the case.
Also, the comments about New York's subways in the story also kind of makes me wonder - when New York lifted for the first time, was it just Manhattan Island? Did some of the other boroughs come along as well? Inquiring minds want to know?
