I don’t write Own Voices fiction, because unless “Fallen Away Actor/Director” qualifies as one, it would be a poor choice.
However, my novels have diverse casts. Luckily for me, I have the perfect critique partner. She’s Bi and her spouse is Trans, making her my own personal sensitivity reader.
It’s amazing how much a writer can miss without that kind of help, whether it’s the simple use of pronouns or more complex emotional issues and life experience.

I am in the same boat re: Own Voices. But luckily have some family members who can advise on non-binary/LGBTQ perspectives. Race and ethnicity is trickier, and yet I feel novels should reflect the world so I try to listen carefully to what people/friends/authors of ethnicities and races different to my own are expressing. After all, I’ve been writing about men for years and years, and god knows they are NOT the same as women.
