So I am rating this 4 stars because I totally got into it by the midpoint and had characters I was rooting for and was following the climate currency thing with fascination, etc. But I can also totally see the flip side, which is people complaining that this is a bunch of tediously and tenuously connected at best. I think it's all down to if you buy into his characters enough to find it enjoyable or not. And that's anyone's guess.
(I will say that regardless the ideas in it are fascinating!)
