The book is not really a novel.
I’m a huge fan of Kim Stanley Robinson, but I almost quit reading a third of the way through. To me it felt like a mind dump of facts, ideas, speculations, possibilities, etc., with a thin plot woven in between. Maybe the author was trying to get all his thoughts about how to deal with global warming down in one place. It was filled with vignettes about the environment, economy, banking, politics, history, terrorism, immigration refugees, and more. But a chapter from the point-of-view of a carbon atom? Come on!
Something that bothers me as an editor is the switching back and forth in style of writing. An example: the use (or lack thereof) of quotation marks in conversation. It takes me a while to tune into a story where the author chooses not to use quotes. It hit me over the head when KSR threw in some chapters where he used them in a book that was mostly written without. One chapter even switched in the middle.
Needless to say, since I finished the book, KSR captured my attention. I learned a lot and was intrigued by his ideas (real or imagined) about how to deal with the world’s environmental, social, and economic problems.
