I’ve seen Rhiannon Held a few times at conventions or readings. Her current book is Tarnished, available at the usual places. She’s given some helpful writing tips on her blog, based on the movie Pacific Rim.
And she appears in period dress
I never saw the movie, and it’s not necessary to benefit from her tips. When she took her first tip from the movie, “Establishing scale” and applied it to writing, I knew she had something insightful going on.
So look at her blog and see if it helps with your overall writing.
