The Seafarer’s Kiss by Julia EmberRead about another entry on the list.
A queer, Norse retelling of “The Little Mermaid,” this novel follows Ersel, a mermaid who longs for a different life outside of the patriarchal mermaid society. Ersel meets Ragna, a shipwrecked Viking shield-maiden who is stranded on the mermaids’ glacier. From Ragna, Ersel learns of the life she wants and strikes a bargain with Loki, the trickster god. Of course, the bargain goes awry. To save herself, Ersel and Ragna must embark on an adventure that involves breaking their societal barriers, trying to outsmart Loki, while falling for each other. This story has lush worldbuilding, and action-adventure and there is a companion novel that tells Ragna’s story, The Navigator’s Touch which has a revenge arc and pirates!
