The Hugo and Nebula Award–winning author and Science Fiction Grand Master delivers a sweeping epic of a planet suffering deadly conditions of alternating extremes

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.

Brian W. Aldiss has, for more than fifty years, continued to challenge readers’ minds with literate, thought-provoking, and inventive fiction. Helliconia Spring’s prescience with regard to climate change is nothing short of extraordinary.
