In one of the coming evenings I will finish my third re-reading of this nice (and thick) trilogy by Brian W. Aldiss, "Helliconia". Recommended. Winner of the John W. Campbell Memorial Award (USA) for best novel of the year 1982, of the Award of the British Science Fiction Association for best novel of the year 1982, and of the Kurt Laßwitz Award in Germany for best foreign novel of the year.

Puts our normal understanding of history into relation a bit.
