I really thought I would like the plot of this book, in a world after global warming where cities were now rafts in ocean and now global cooling is an issue! There are definitely many talking points about climate change brought up in this book. However, some of the plot seems to be all over the place. The main character Sal, wants to fit in with the ocean and becomes genetically altered in order to do so. This is another great discussion! However, the characters aren't quite developed enough to fall in love with. The writing also seems to be on a Young Adult level; however, the way sex is approached in this book does not make it suitable for that audience.
With some clean-up, I would be interested in a sequel to Cities at Sea since we left the characters in a precarious situation. There is definitely room to grow.
