Sold as a reading copy: Expect all flaws. See pictures. The satellite-sized alien Gaea has gone completely insane. She has transformed her love of old movies into monstrous realities. She is Marilyn Monroe. She is King Kong. And now she must be destroyed. Demon was first published in 1984 and completes the trilogy of humanity's encounter with a living being in the shape of a 1,300 km diameter Stanford torus, inhabited by many different species such as the centaur-like Titanides, living blimps, iron masters, and the god-like, insane entity known as Gaea in orbit around Saturn. The protagonist of the trilogy is Cirocco Jones, a charismatic but complex super-hero who displays a dramatic counter figure to the deliberate antagonist of Gaea. The real quality of the trilogy is Varley?s wonderfully imaginative, uniquely original world building. Cirocco Jones is something around a hundred and twenty years old at this point and she's completely turned on Gaia who seems to be going batshit crazy. If you don't believe me, check out her children, her affair with King Kong as a 50 ft Marylin Monroe, or her myriad lies or new fascinations. She's been around a long time. She's also a fan of the human culture. Gaia's a big fan of movie monsters and science fiction epics and doesn't mind playing around with all the creations in the world to fill her whims.
