@shadowsminder Off the top of my head, I’d go: Claudie Arseneault, RoAnna Sylver, mine, Rosiee Thor, Claire Kann, Alechia Dow, and Darcie Little Badger. That’ll make up a solid starter pack, but let me know if you want specific genres or more details because most of those are sff. Most of the books by these authors feature multiple aspec characters in leading roles, all will at least prominently feature aspec themes.
Claudie has also been doing a series of posts called #ASpecToZ that has a whole bunch of solid, additional recs to consider as well.
