Perhaps some might guess that NY 2140 was not my cup of tea - and I don't drink tea.
As a thriller it has lots of faults: slow pace, punch of suspense repeatedly pulled, characters not either well developed or interesting and a lot of dry exposition.
There are a couple of villains in the book: finance and capitalism. I have my problems with both, but the author, I think, doesn't really understand what he is talking about.
So what about the future world he created? It's wetter, sea level having risen 50 feet or so, but somehow, much of the drowned part of New York and other cities continues to be occupied. This is probably more interesting to those intimately familiar with the geography of the city than to me, a fairly infrequent visitor. It's a largely post carbon burning world, but I didn't find that especially interesting either.
