New York 2140

New York 2140 by Kim Stanley Robinson, 613 pages.
Two coders living on a rooftop in the flooded remains of Manhattan in the year 2140, believe that they have found a way to change some of society's fundamental rules. Turns out they are wrong, and they quickly realize this. In the aftermath of the events resulting from their mishap, Amelia Black, star of an internet wildlife rescue show; Gen Octaviasdottir; a police inspector, Franklin Garr, Lord of the Intertidal, an quant; and Charlotte Armstrong, a politically connected activist, all cross paths. Things do begin to change then in this enjoyable, but somewhat didactic tale of a future and waterlogged NYC.
