This was a pretty disappointing read. The protagonist was . . . difficult to like or empathize with. I also didn't really believe in the world the author had created. Set maybe 50-60 years in the future, after climate change created an ice age all over the US, 20,000 people made it to a far off and uninhabited island that they proceeded to completely trash. Somehow, they were still able to have beef and tobacco and cheese [food], and young people understood tons of references to things that are happening now and in the recent past. The protagonist ends up as a heroine though it's completely unclear to me how's she has become one or what she's done that's any different from what anyone else has done. Unsatisfying.
