Navigating the Tides of Change In Eliza Chan’s Fathomfolk

In the fictional city of Tiankawi, the world is sharply divided between those in power and the second-class citizens, often refugees or the children of refugees, who are prohibited from holding high positions and frequently kept from finding reliable, safe work. But what makes this familiar setup enchantingly unique and vibrant in Eliza Chan’s debut novel, Fathomfolk, is that the second-class citizens are people of the sea: sirens, mermaids, kappa, dragons, and more. These people, identifiable even in convincing human form by their signature gills, aren’t all one group or culture. They’re multifaceted, from many different havens in a world overrun by polluted waters. They’re folk—properly the fathomfolk of the title.
Chan launches readers into the scene immediately, starting with the promotion ceremony of Mira, a half-siren who is native to Tiankawi. Over the years, she watched her siren mother struggle to make ends meet, and she wanted better for herself. More. Determined to be better than her classmates, even without using siren powers, she succeeded well enough to become the first fathomfolk captain of the border guard—a second-class law-keeping unit when compared to the city guard, but it’s something. Mira believes that by proving her worth on human terms, she can make a difference. She, alongside her ambassador boyfriend, a water dragon named Kai, can fight for change that will make the lives of fathomfolk better. More equal.
But change like that takes a long time, and it’s not happening fast enough for Kai’s hotheaded sister, Nami. Exiled from their haven after one of her rebellious statements goes too far, Nami is sent to Tiankawi to discover how humans have mastered energy production, and how the havens could compete with it. But Tiankawi is overwhelming for someone who came from a privileged life in the havens, and her anti-authoritarian drive sends her into the arms of Tiankawi’s most militant fathomfolk rebel group. At first, Nami does her best to stay on track, even studying in the library with devotion despite not being a natural scholar. But when she’s stymied, she feels like the resistance gets her in a way that her diplomat brother and his law-keeping girlfriend don’t. It doesn’t hurt that one of the members of the resistance, Firth, makes her think first with her body and only later with her brain.
Working the system for the betterment of all doesn’t appeal to sea witch Cordelia, either. It doesn’t matter whether her clients are human or folk, no one truly trusts a sea witch. She’s met with spite and wariness everywhere she goes. So if anyone’s to be looking out for her, she has to be the one to do it.
And for the wife of the head of all military forces in Tiankawi, the real trick is keeping her family elevated. Serena manipulates and connives to make sure her husband and adult son climb the ranks within the government and the city guard, and she makes plans that will give her daughter the best future possible. What happens to the folk is really not her concern, so long as her family is cared for.
