Critical Mass is a very good second book in the Delta-v series. While very good fiction, it is intended to be a realistic telling of what could be possible in addressing climate change if a motivated, small group of people go outside of norms to achieve their goals.

Some of the plot point are deliberately optimistic, but in the afterword Daniel Suarez wrote that was deliberate in an attempt to inspire people to action.

My only quibble was the simplistic handwaving around the how cryptocurrency magically makes the economics work in favor of the protagonists.
