An obscure sci-fi novel from the 1970s, filled with explicit portrayals of teenage sex slaves, breeding clinics, and aristocratic predators, is gaining unexpected attention online.

Conspiracy theorists have drawn eerie parallels between its disturbing plot and Jeffrey Epstein’s real-world sex trafficking ring.

The novel in question is “Space Relations: A Slightly Gothic Interplanetary Tale,” which was released in 1973 by Donald Barr, previously a headmaster at a New York City prep school and the father of Bill Barr, the Attorney General during Trump’s tenure. It has become the focus of numerous online debates.

Adding to the intrigue is Donald Barr’s past as a former CIA officer and his role as headmaster of the esteemed Dalton School on Manhattan’s Upper East Side, the same period when Jeffrey Epstein was employed there as a teacher, notwithstanding his lack of a college degree.

Though Donald Barr had stepped down by the time Epstein was hired, conspiracy theorists have seized on the timing, the lurid novel, and his son Bill Barr’s role in Epstein’s 2019 death in custody — as proof of a sinister connection.

‘The Internet is abuzz with many bizarre theories,’ reviewer Justin Tate posted on Goodreads about the 250-page book, which is now being sold online for as much as $4,000 a copy.

‘Some read Space Relations like it’s the Da Vinci Code, with hidden clues that might even reveal who killed Epstein. Others marvel over loose connections between Barr’s plot and Epstein’s crimes.’

What has most stunned readers is how eerily similar the fictional universe is to the real-life sex trafficking empire run by Epstein, who abused scores of underage girls in New York, Palm Beach and his now-infamous private island.

The plot of Space Relations follows John Craig, an Earth diplomat captured and enslaved on a distant planet called Kossar, where the ruling aristocracy maintains a brutal regime of sexual domination and forced breeding.

Craig ultimately becomes a servant to Lady Morgan Sidney, a sadistic elite described as having ‘high breasts and long thighs’, and is compelled to rape a teenage slave girl as part of an intergalactic breeding clinic.

Critics have called the book ‘cheesy’, ‘bad writing’ and ‘incredibly creepy’ — but that hasn’t stopped a cult following from forming among collectors, conspiracy theorists, and critics of America’s ruling class, who say the novel reads more like a disturbing prophecy than fiction.

Just one year after Space Relations hit shelves, Donald Barr was headmaster at Dalton. 

In 1974, Epstein, then a college dropout in his early 20s with no teaching qualifications, landed a job there teaching math and physics.

His brief stint at the school is widely seen as the springboard for his later social climbing — and grooming.

It’s never been definitively confirmed that Donald Barr personally hired Epstein. But it’s that foggy link — between the bizarre content of the novel, Epstein’s inexplicable employment, and Bill Barr’s involvement decades later — that has sent the internet into a frenzy.

Following Epstein’s death at the Metropolitan Correctional Center in New York in August 2019, then-Attorney General Bill Barr promised a full investigation, calling the circumstances a ‘perfect storm of screw-ups’ — including non-functioning security cameras and asleep guards.

He ultimately accepted the ruling of suicide, despite widespread doubts and calls for deeper scrutiny.

Recently, conservative YouTube host Tucker Carlson featured a segment exploring the connections, interviewing controversial history podcaster Darryl Cooper, who called the coincidences ‘very strange and unacceptable’.

Cooper questioned Bill Barr’s motives for dismissing Epstein’s death as a ‘suicide before they’d finished the investigation.’

‘It could all be a coincidence, but the odds are against that,’ said Cooper.

The claims have been debunked by fact-checkers, including Snopes, which labeled the theories ‘mostly false.’

There is no proof Donald Barr, who died in 2004, played a role in Epstein’s hiring, nor are there strong similarities between the fictional interplanetary sex ring in Space Relations and Epstein’s real-life criminal enterprise.

Still, for a novel that once gathered dust on the back shelves of second-hand bookstores, Space Relations has found a strange second life — not as science fiction, but as the focus of one of the strangest conspiracies of the post-Epstein era.
