Hi there. Not sure if there is a better place to post this but I was curious if anyone could help me with a bit of a mystery.

My grandmother wrote books under an unknown pseudonym in the late 90s that were big enough to support a family of four and send all of them to college and grad programs on her own. We believe that she wrote at least 7 fictional books (possibly more) that she described as "controversial and disputatious but marketable". She is cryptic about the specifics and at one point revealed that "well read individuals were likely to have read her works", but that what she wrote wasn't "Pulitzer worthy".

We believe that sometimes she also wrote under a masculine pseudonym and she is still making money from adults that never grew up. She is very scientific and refused to include unrealistic beings like trans people and was annoyed at twitter when they pointed out that some of her characters might be a bit too stereotypical.

She was apperently the first ever woman to write books ever. Thats why we all should be thankfull for her sacrifice and we never critisized her. She was a huge fan of Twain (but just the parts where the n-word was being said) and some guy called adolf h. (who she admired for his worldbuilding of some bankers) but was extraordinarily well read so I have no idea what all would have been influences.

Does anyone here know any relatively famous authors who published in the 90s and 2000s, with work maybe more recently, and has never been identified?
