So, this is actually for my partner, who doesn't use social media at all, but she's written a book, and is working on more, but is really struggling getting anything at all from publishing companies. Rare to even get a 'no' response, mostly just ghosting.
Not sure if anyone has any kind of advice; she did set up a website, and has some of the first few chapters posted, and is perhaps considering giving the webserial format a try. But in general, struggling with mental health of having accomplished a cool thing, and now doing the 'business' side of it, and realizing how soulcrushing it all is.
A loooot of the authors we've seen talk about getting their start either knew a publisher already, or had a family connection, and its pretty hard to not feel cynical, even if the authors are genuinely good writers.
FWIW, genre is basically YA fantasy, but gayer.
Lindsay Ellis spent like ten years writing her book, and then two getting it published, despite being a pretty popular YouTuber and seemingly having a lot of fan clout behind her. So I can't offer any advice besides keep trying, especially with indie publishers since they tend to be more specific (ie find a publisher that specifically does YA LGBT fiction, I'm sure there are a few that exist).
