Glasshouse is a science fiction novel by British author Charles Stross, first published in 2006. The novel is set in the twenty seventh century aboard a spacecraft adrift in interstellar space. Robin, the protagonist, has recently had his memory erased. He agrees to take part in an experiment, during which he is placed inside a model of a late twentieth/early twenty-first century Euroamerican society. Robin is given a new identity and body, specifically that of a woman named "Reeve". Major themes of this novel are identity, gender determinism, self-image- and conformity. Contrary to popular belief, it is not a sequel to his 2005 novel Accelerando, although Stross has stated that the two novels are not obviously incompatible. Glasshouse was nominated for the Hugo, Campbell, and Locus Awards in 2007.
