Blue Mars - Kim Stanley Robinson

The last of the trilogy. With Mars terraformed, the few remaining first hundred and their native born successors are faced with more political challenges from an over crowded and envious earth, and fundamental decisions as to how to make the most of their independence when there are such a range of views amongst the martian communities.

Not as dry as it sounds - and I really enjoyed seeing the characters and situations evolving over a further century (thank heavens for the longevity treatment, even if it is an easy fix....). The only thread left dangling loose: what did happen to Hiroko?
