Pol sci fi, environmental--The Wind Up Girl--novel

https://www.amazon.com/Windup-Girl-Paolo-Bacigalupi/dp/1597801585 I am trying to decide from the opening pages whether I like it as much as Justin Cronin The Passage series or Game of Thrones or Drowned World, Flood, Ark or Death of Grass. I think probably Flood and Death of Grass are the most compelling, Game of Thrones, the first book with the best opening. Anyway, it's subjective as the agents like to say. km
