How Does Our Wives Under The Sea Use Underwater Settings To Build Suspense?

Having just finished it, I'm struck by how it's a book that somehow makes the vastness of the ocean feel like a suffocating interior space. The obvious theme is grief, but it's not the loud, dramatic kind. It's the quiet, creeping horror of living with someone who has returned but is fundamentally, irrevocably altered. Leah comes back from a deep-sea expedition that went wrong, and she's just... not right. Miri has to care for this person who looks like her wife but is slowly becoming something else, leaking saltwater and drawn to the dark. The domestic horror of that daily erosion is more terrifying than any monster. I think a lot of genre labels get slapped on it—cosmic horror, queer fiction, literary fiction—but at its heart, it's about the failure of language. How do you articulate a loss when the person is physically present? Miri tries to communicate, to understand, but Leah's experience is literally unspeakable, locked away in the crushing pressure of the deep. The novel itself becomes an act of translation, trying to find words for a trauma that exists beyond human scale. It also, in a weirdly tender way, explores devotion. What does 'in sickness and in health' mean when the sickness is a metaphysical transformation? The love isn't gone; it's strained and warped, but it persists, even as the familiar shape of the relationship dissolves. It's also a sharp critique of institutional neglect. The shadowy marine research centre that sent Leah down is totally absent in the aftermath, leaving Miri alone to deal with the fallout. That feels incredibly modern—the way systems extract what they need from people and then abandon them when they break. The prose is so clean and precise, which makes the surreal, bodily horror of Leah's change even more potent. It lingers, like salt on your skin.

I found the marine biology metaphors in 'Our Wives Under the Sea' to be the most haunting part of how it handles trauma. It’s not about loud breakdowns, it’s about the quiet, crushing pressure of the deep sea, which Miri feels as Leah comes back changed. The prose itself feels waterlogged, heavy with unsaid things. Miri’s chapters, all that domestic routine of making smoothies and trying to connect, are just layers of sediment piling up over this massive, unprocessable event. It’s a story about the aftermath, where healing isn’t a linear path to sunshine but learning to breathe in a new, strange atmosphere where your loved one is now a kind of alien. What struck me hardest was how the book refuses to give a neat explanation. Was it a psychological break, a cosmic horror, or something literal? The ambiguity forces you into Miri’s headspace of just not knowing, which is a core part of trauma—the inability to make a coherent narrative of the hurt. Healing here isn’t about ‘fixing’ Leah or getting answers. It’s about Miri slowly, painfully, accepting that the person she married is gone, and building something new with the person who returned, even if that new thing is fragile and strange. The final scenes on the beach don’t feel triumphant, just achingly tender in their acceptance of a profoundly altered reality.

It’s strange, I finished this a few weeks ago and my brain still pulls up little moments from it when I’m doing the dishes. The romance isn’t about the start of something, it’s about the terrifying, slow erosion of a thing that already exists, and that’s what ties it into the mystery for me. Leah comes back from a deep-sea mission that went wrong, and she’s… not right. The mystery is what happened down there, but it’s also the mystery of what’s happening inside her apartment, to her body and her mind, and whether the woman Miri loves is even still in there. It gets under your skin because the horror is so domestic—Miri trying to feed her, listening to the strange sounds from the bathroom, noticing the saltwater. Most genre blends feel like you get a chapter of one thing, then a chapter of the other. Here, they’re the same substance. Miri’s love is her investigative tool; every act of care is a data point in trying to solve her wife. The oceanic dread isn’t a separate plot, it’s the metaphor for the unknowable parts of a person you’ve shared a life with. Even the structure reflects it, with Leah’s clinical mission logs against Miri’s crumbling, present-tense worry. It leaves you with this heavy, beautiful ache that’s less about solving a puzzle and more about sitting with the fact that some puzzles can’t be solved, only tended to, like a strange tide pool in your own living room. I still think about the bathtub.
