Green Mars

Amazed once again by Kim Stanley Robinson. The books in this trilogy are so long, I catch myself drifting in and out of focus while listening. But that even seems okay as the plot shifts in intensity, giving you a tapestry of the ecological and governmental developments over a next half century.
Yet again, this is deliciously equal parts science and sociology, the creation and controlled management of systems of atmospheres and people. While Mars undergoes a potential phase change so does its population as they argue, organise and revolutionise their way towards a Martian independence from Earth. Yet what independence to choose?
