In 1973,
Kirkus Reviews described the novel as "a coruscatingly literate tale for grown-ups". In 2008, the novel was criticized by
Pornokitsch for devoting too much attention to character development rather than world-building. The review notes that the narrative is split in two, between the present-day official visitation of Craig to the planet Kossar, and his past experiences as Lady Morgan's slave. Becky Ferreira has described the novel as "highly unsettling", due to its depiction of rape of enslaved people, particularly teenage girls, and other coercive sex acts. The sex acts described are performed "for the dual purposes of entertainment and controlled procreation". Ferreira found disgusting the novel's fixation on the
sexualization of adolescents. She notes that the adult characters are subjected to
infantilization. The novel's dialogue includes "casually unsettling observations". She cites as an example a character remarking that
pederasty lacks "aesthetic appeal". She views the novel as sexualizing minors and fetishizing rape.
Space Relations saw increased public attention after
Jeffrey Epstein died in jail. Despite his lack of credentials, Epstein was hired to teach at the
Dalton School. In February 1974, Mr. Barr had announced that he was resigning as headmaster, protesting the meddling by the board of trustees, but that he would stay on until the end of the school year. It is unclear whether Mr. Barr hired Mr. Epstein during that time. The similarities between the violent sexual depictions in
Space Relations, Epstein's sex trafficking activities and obsessions, and the crimes of his associate
Ghislaine Maxwell, have all led to increased public scrutiny about Epstein and Barr’s relationship. Sellers of
Space Relations on
eBay explicitly advertise its connection to Epstein in their descriptions of it. It was also included as a key plot point in the season 4 finale of the legal drama
The Good Fight. ==References==
