Walden
In a near-future with worsening climate change and refugee crisis, and where synthetic foods, cloning, and war are common, Cassie, a NASA astronaut returned from a year-long lunar mission, visits her estranged fraternal twin sister Stella, and Stella's partner Bryan, at a remote cabin. Stella, a former NASA architect, designed a Mars habitat called Walden while at the agency. Cassie is about to begin training for a mission to Mars, where she will live in the Walden habitat. Stella, while still believing in NASA, now favors prioritizing the Earth, while Bryan is an "Earth Advocate" activist, and they argue with Cassie about space colonization. A love triangle develops.
