Hi! I'm new to the forum and just found this post. Maybe my novel qualifies:
My "Lucky Wolf" a historical novel set in the Viking Age! It's an adventure tale with some dark themes and (gay) romance, showing the relationship between Eyolf (a poor orphan who becomes a thief, a prostitute, and eventually a wealthy and famous mystic) and Yngvar (a warrior nobleman). It's fully realistic (no fantasy, just well-researched historical fiction), but I hope the mature themes (violence and sex) aren't a problem.
You can check it out here: LUCKY WOLF https://tapas.io/episode/1435130
It is also illustrated in a parallel series: LUCKY WOLF [EXTRAS] https://tapas.io/episode/1617732
I'd love to share feedback with authors of similar stories!
