I am working on the sequel to Murder in the Tool Library, a solarpunk mystery novel I published recently. In the next book, the clues lead to the Yucatan, and I would love to improve my representation of native people from that region. If you identify in any way as Maya (Yucatec, Mopan, or Q'eqchi') please do message me.
I don't know anyone. Is there an agency or community for this? Have you looked for any indigenous literature communities on FB or Reddit?
My husband is reading an anthology of Indigenous horror stories called "Never Whistle in the Night". Maybe the publisher or contributors could put you in touch with some folks.
