Helliconia is Big, not just in pages, size of planet or time scale covered, but in number of themes it tackles. Other reviewers have complained about the thinness of character development. I think they miss the point, the people in Helliconia are all too human, flawed and weak. Do we really need yet another scifi series full of epic all conquering heroes. Yes plotlines peater out, but isn't life like that, lots of incomplete experiences ? Early in the first volume the new leader of the town and a highly intelligent women's , initial closeness turns to astrangement, bitterness and eventual regret for what might have been. Who hasn't experienced sometime similar ?
Above all for me the books are about the context within which we and the characters live in. Helliconia's extremes means its peoples have to navigate a perilous course over generation upon generation with many setbacks. Most helliconians cannot see the context within which they live, just the consequences of the enormous forces at work. In contrast the humans that observe helliconia, do so from a serile technological world that never changes; they live within no context at all. These two themes
mend there way through much of the books. Though there's much more here for all sorts of readers.
Helliconia is a work of imagination and ideas. The very things I need from reading. Its almost the perfect Scifi paradigm, in comparison much modern scifi is just cowboys and indians in space or indeed therapists on starships.
