I just finished The Dervish House by Ian McDonald.

Set in a near future Istanbul, were nano-tech is a cottage industry, The Dervish House follows a number of plots centered around one home.  These include the launch of a new tech product, the search for a man turned into honey and the fallout of a tram bombing.  They all tie neatly together in the end.

A dense, slow read, but worth the effort.  Expected to be on a lot of end of the year best of lists.
