“A trailer for a book? Really?”
Trailers for movies have been around for a long time, but it wasn’t until video distribution became simple in the mid-2000’s (especially in the advent of YouTube) that book trailers came into existence.
For Heretics of Piedmont, I read from multiple sources that a trailer is helpful, but not totally necessary. I didn’t pursue it until just before that book’s release in September 2021. Video production is not at all something I was comfortable with, so I scoured Fiverr for a seller who could develop in a style I liked.
