Glasshouse (novel): 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.

Lovecraft", it was the album's longest track, and an edited version was also released as the band's second single.  The name and theme of the song derive directly from author H. P.
