This book reads like it was written by someone with a PhD and sure enough that’s what it was. It’s a “hopepunk” story about a future world ravaged by climate change and people trying desperately to create enough sustainable energy to power the planet. But something’s affecting the AI-managed power grid, and power engineer Lucia Ramirez is determined to figure out what is going on. A lot of explications of various energy options, wonky but ultimately a good story.
