Yes I have a few of the Gor Novels by John Norman and frankly they reminded somewhat of those old Greek, Roman and Barbarian movies from back in the 60's.One distinction here to keep in mind,is that these Gor Novels were written by John Norman.There is an author out there by the name of Jack Norman,who happens to write some rather intense S&M themed novels.Just to confuse the similarity in names is the fact that one of Jack Norman's novels is titled "The Gorean Club".
For those into post apocalyptic scenarios ,Jack Norman wrote a novel titled "2084" . In this one the surviving "haves" build a protective dome to keep out the surviving "have nots" and within this dome,slavery is institutionalized and also is widely practiced by the "have nots" outside the dome.Caught in the middle of all this is Leila Ashe,who finds herself enslaved by the high tech enslavement methods in the dome and then falls under the hands of the "have nots".
Another novel that delves more into the near future is "Emily's Debt" by JJ Argus.In this one "Emily",a young female college grad has a huge college loan to pay back and no job with which to pay back these loans.Indebtedness has become so prevalent in this near future economy,that laws are passed wherby debtors can be arrested and forced to work off their debts.Emily winds being sold to a former classmate who has become a lawyer,one who pushes the limits of the debt slavery laws with some his sadistic demands he imposes on Emily.
