Sorry to take so long to respond! It’s a novel set in a plausible near-future in which existing power structures have been fragmented by the effects of climate change. It follows a handful of disparate characters in the western US, and talks a lot about the water politics of the Colorado river. It’s very well-written (claims random internet guy, but hey—you asked!). Can also recommend The Windup Girl by the same author. Same eco-dystopian timeline, set in Thailand. Delves more into issues surrounding AI and genetic engineering.
