I am a developmental editor and I edit query letters. I primarily work in the sci-fi genre, and all subgenres are welcome. I also take on some fantasy (including romantasy), but I am a little choosier with these. In all genres, I only work in the adult or new-adult categories.
I do not generally edit work that falls outside of the umbrella genres of sci-fi and fantasy. I also do not edit middle grade, young adult, erotica, or horror. As a rule, I do not take on work that endorses homophobia, racism, or sexism (dealing with these topics critically is fine, but I don't take on work that endorses these ideologies). I also do not take on work that deals with cancer of a main character or depictions of sexual assault.
