The main idea behind this novel is pretty straightforward - it uses the seed vault on Shearwater Island and the Salt family’s story to explore how climate change could threaten humanity’s future.
But honestly, with all the debate around climate issues these days, I couldn’t help but wonder - does this kind of big, dramatic narrative still land the way it’s meant to? There’s been growing skepticism around the whole “climate crisis” concept, and it’s stirred up a lot of cultural and economic controversy. So from that angle, the book’s foundation feels a bit wobbly to me. And since the story keeps leaning hard into that theme, I found it tough to fully connect - it just didn’t pull me in emotionally the way I hoped.
That said, McConaghy’s writing is seriously impressive. Her nature descriptions are vivid and immersive, and she’s got a real knack for digging into her characters’ inner worlds. Dominic, Rowan, and the 3 kids - are all distinct and well-developed. She really captures the emotional tension that comes with isolation, and her prose has this quiet strength to it that I really appreciated.
Where the book stumbles, though, is pacing. The first half drags quite a bit, and the suspense takes forever to kick in. There’s a lot of introspection from different characters, which adds depth but also slows everything down. At 1 point, I was worried it might veer into soap-opera territory - especially when 1 character who was totally against having kids suddenly has this dramatic maternal awakening. That twist felt a little too on-the-nose.
For me, the real standout isn’t the climate message - it’s actually the island itself.
This remote, frozen place, with its brutal winds, icy waters, and wild animals, makes for an incredibly cinematic setting. I could totally picture the camera sweeping over penguins and seals, with a storm brewing in the distance. The island isn’t just a backdrop - it’s like a character in its own right. It cranks up the tension, magnifies the fear and trauma, and brings out both the cracks and the resilience in the people stuck there.
That strong sense of place made it easy to feel for the researchers, who are clearly stretched thin by the isolation, the pressure, and the loneliness. Their slow unraveling felt way more real and compelling to me than the sudden love stories.
Thankfully, the ending sticks the landing. The story zooms in on a powerful question - how do we protect the people we love when everything’s falling apart? It’s a sharp, emotional finish that really lifts the whole book and brings its human themes into focus.
At its heart, this is a character-driven novel. The plot isn’t super twisty, but the mood and emotional depth are where it shines. McConaghy tries to juggle a lot - climate disaster, family wounds, broken trust, surprise romance, and a late-in-the-game motherhood arc. But the real strength of the book isn’t in trying to sound the alarm about climate change - it’s in how it makes me sit with people who are just trying to hold it together in extreme circumstances. That kind of raw, honest storytelling is what sticks with me.
Even though I wasn’t totally sold on the book’s core message and found some of the plot turns a bit clunky, I’ve got to admit - it’s a well-written, emotionally rich read. If you’re open to its perspective and can hang in there through the slow start, the payoff in the second half might just be worth it.
3.4 / 5 stars
