The Stone War by Madeleine E. Robins
A spooky book. In the unfortunately not too distant future, architect John Tietjen lives in and loves New York City, in spite of the homeless on every street, and the gangs on every other street, and the security guards on every street corner. Then things really go to the dogs. When John is out of town on a job, some mysterious force unleashes true evil on the city by way of earthquakes, flooding, and an horrific force creating monsters of many of the few people left living. John makes his way back to help the survivors take back their city. Dystopian, horror, fantasy, mystery, noir, there are too many labels to choose from, but here's another one for you: Mesmerizing.
