(1984) It's a collection of three interconnected novellas, about a failed revolution on Mars and what happens after, set in the 23rd-27th centuries. The “icehenge“ of the title is a megalithic structure on Pluto, which may have been constructed by Martian rebels, or by aliens ancient or recent, or something else. I quite liked the premise and the epistemological themes, but found it difficult to engage with the story.
