5 Mermaid Fantasy Books to Add to Your TBR (YA & Adult)
A Spell for Drowning by Rebecca Ferrier
The people of Portscatho are deeply tied to the sea and its traditions, living alongside spirits, gods, and monsters that inhabit the stormy waters around them. When Kensa and her stepsister discover a dying sea creature on the Cornish coast, Kensa claims the credit, stealing both recognition and the chance to become the village sage’s apprentice.
The role seems to suit her, especially as someone who has always felt like an outsider. But becoming a sage comes at a cost: a life of solitude, with no family of her own and little love from the community she serves. Her only true companion is her mentor, Isotta.
When Isotta falls gravely ill, Kensa is willing to do anything to save her and to secure her place in the village. Even if it means turning to the Bucka, a dark and unfathomable sea god who rules the tides. But such bargains come at a price, and Kensa risks losing everything she swore to protect.
A dark and atmospheric mermaid fantasy that leans into the realm of dark fantasy… definitely one for your wishlist!

When a coup strips her of everything—her crown, her family, and her home—Yemi is left with only one possible ally: Ursula.
