Glimmer by Marjorie B Kellogg is a recommended character driven climate science fiction novel set in NYC in 2110.
Rising sea levels, superstorms, and a changing climate have left much of the city wrecked and/or flooded. Those who could fled the city. The survivors left behind have banded into their own social support structures called dens. Members of the dens live on the upper floors of buildings and work together to find supplies and food, while protecting each other. Glimmer, a name she gave herself after she lost her memory, is a young woman living in this dystopian future. She is part of one of the oldest dens, Unca Joe, and has her friends and support system there. It is an unpredictable life, but every now and then Glimmer senses that she recognizes something from before. But when it seems that another group is planning some attack against her den perhaps she does need to consider a change.
