The Helliconia Trilogy

Helliconia follows an eccentric orbit around a double-star system with a twenty-six-hundred-year cycle of very long seasons. As spring slowly breaks the brutally long winter, humans emerge from hiding and a long sequence of civilization and growth begins to repeat again, unbeknownst to the participants but watched by an orbiting satellite station, Avernus, created by Earth some centuries ago. Humans free themselves from slavery to the aboriginal Phagors, and religion and science flower and expand.

This is the first volume of the Helliconia Trilogy—a monumental sage which goes beyond anything yet created by this master among today's imaginative writers. An entire solar system is revealed, and with it a world disturbingly reflecting our own, Helliconia: an Earth-like planet where dynasties change with the seasons.

A handful of centuries on, Helliconia is close to the larger star in its binary system, and the Phagors have been driven into exile, but conflicting religions and hostility to science keep human civilization fragmented and constantly fighting wars over petty power and fertile land as a plague devastates populations. However, everything changes when a secret visitor from the observer satellite from Earth accepts a slow death in order to visit the planet and spend his time in the sunlight and open air.

The third and final instalment in the epic Helliconia trilogy. The centuries-long winter of the Great Year on Helliconia is upon us, and the Oligarch is taking harsh measures to ensure the survival of the people of the bleak Northern continent of Sibornal. Behind the battle with which the novel opens lies an act of unparalleled treachery. But the plague is coming on the wings of winter and the Oligarch's will is set against it — and against the phagors, humanity's ancient enemies, who carry the plague with them.

After many centuries, the flowering of human civilization has begun to dwindle again and the Great Year slowly progresses while the long, deadly cold winter looms—but a break in the long, repeating cycles of growth and decay may result from the long-ago visit of the Earthman. New legends of the spring and summer have evolved and a new future may be aborning.
