What Are The Best Fantasy Books Mermaid Fans Should Read?

For a classic fantasy feel, Christelle Dabos’s 'The Missing of Clairdelune' (second in 'The Mirror Visitor' quartet) has some breathtaking merfolk societies, though they’re not the main focus. The world-building is exquisite—floating celestial arks and complex court politics—and the scenes set in the underwater citadels with their tide-manipulating nobles are some of the most vividly imagined in the series. It’s a great pick if you want mermaids woven into a larger, intricate fantasy tapestry.

I feel like a lot of recommendations always go straight to YA or romance, but the mermaid-adjacent book that genuinely captivated me was 'The Deep' by Rivers Solomon. It’s a novella, so it’s a quick read, but the density of its ideas is incredible—it ties merfolk mythology to the historical trauma of the Middle Passage, with a society built from the memories of drowned enslaved women. It’s fantasy, but it’s also profoundly speculative and literary. The mermaids (or wajinru, in this case) are so far removed from the typical imagery; they’re these deep-sea, collective-memory beings. It’s not a light, escapist read by any means, but it’s arguably one of the most important and creatively ambitious takes on the concept in recent years. It definitely pushed me to think about the genre in a new way, wondering what other historical or cultural depths these myths could be used to explore.

Don’t sleep on 'Into the Drowning Deep' by Mira Grant. It’s a horror-thriller about a scientific expedition to the Mariana Trench to find out what really happened to a previous crew that was slaughtered. The mermaids here aren’t romantic; they’re hyper-intelligent, predatory, and terrifying. It’s all about the suspense and the creeping dread as the ship gets further from help. If you like your fantasy with a serious side of creature-feature tension, this is the one.

Okay, I might be the odd one out here, but I often find the human-centric mermaid stories a bit dull. My absolute favorite is a progression fantasy called 'The Mer Crown' on a serial site. The entire narrative is from the perspective of a young mer-guardian who has to level up her hydrokinesis to defend her reef city from a leviathan. It’s got LitRPG elements—like stat screens for her sonic calls and symbiotic relationships with giant clams—which sounds silly, but it’s shockingly immersive. The author puts so much detail into the ecosystem, the politics between different mer tribes, and the magic of the abyssal zones. It’s a completely different vibe from a surface-world romance; you’re fully submerged in their culture, their problems, their magic. Sometimes I just want to forget the land exists altogether, and books like this deliver that perfectly.

Mermaid fiction kind of splits into a couple distinct camps that scratch different itches for me, and I’d need a whole bookshelf to cover them all. First, the coastal gothic or historical fantasy take, like 'The Mermaid of Black Conch' by Monique Roffey—less about sparkly tails and more about loneliness, obsession, and being a creature out of time. It’s got this haunting, literary vibe that sticks with you. Then there’s the pure romantic fantasy side. 'To Kill a Kingdom' is basically a Little Mermaid retelling but with pirate princes and heart-stealing siren royalty; it’s all banter and dark oceanic magic.

But honestly, if you want something truly unique in the fantasy space, you should look into some of the indie-published stuff on platforms like Royal Road. There’s a whole niche of ‘merfolk civilization’ stories that build entire underwater societies, magic systems based on tides and bioluminescence, and political intrigue between different oceanic clans. It’s less romance-focused and more world-building heavy, which I personally love. Sometimes the big trad-pub books feel like they’re just retreading the same old fairy tale, while these web serials go off in wild directions, like a merfolk protagonist who’s essentially a deep-sea archaeologist uncovering drowned cities. That sense of discovering a fully realized, alien world beneath the waves is what I’m usually hunting for.
