Patient Setup, Devastating Payoff
I'll be honest: this book takes its time. The first half is all atmosphere and character work - a recent college grad navigating a world where she doesn't quite belong, a fourteen-year-old desperate to be seen as grown up, a Vineyard summer unfolding in long beach days and awkward dinner parties. If you need action immediately, you'll get restless. But Spiro is building toward something, and when she gets there, it hits hard.
Lindsey has an art history degree and no connections. Georgie has every privilege and no idea what to do with it. They shouldn't have much in common, but that summer they find each other - the nanny who feels like a fraud among the wealthy, the teenager who feels invisible in her own family. Their friendship develops with the kind of easy intimacy that only happens when you're both a little lost.
Then there's the night at the lighthouse, and everything breaks.
The Ten-Year Silence
Spiro's smart decision is jumping forward a decade. We know something terrible happened, but we spend the first half of the book watching it approach rather than watching its aftermath. The dual timeline creates genuine tension - not mystery about what occurred, but dread. You see these two forming a bond and you know it won't survive what's coming.
What I found most effective was how the book captures the particular silence around assault. Not the event itself, but why people don't speak. Lindsey's reasons are different from Georgie's. Both make a kind of terrible sense. The way power and money complicate everything, the way victims convince themselves it wasn't that bad or that no one would believe them - Spiro gets this right without being heavy-handed.
The Vineyard as Character
Spiro lives on Martha's Vineyard year-round, and it shows. This isn't postcard tourism - it's the island's class structure laid bare. The summer people with their beach clubs and networking events. The year-rounders and seasonal workers who make it all run. The way money creates invisible walls even in supposedly shared spaces. Lindsey navigates this divide all summer, never quite sure which side she's on, leveraging connections while resenting the system that makes connections necessary.
Georgie's teenage restlessness felt real to me - that particular fourteen-year-old desperation to be taken seriously, to be part of something beyond her parents' world. She romanticizes Lindsey's independence without understanding that Lindsey's "freedom" comes with uncertainty and precarity Georgie has never had to consider.
The Flaws
The ending wraps up a little too neatly. After all that patient buildup, the resolution felt rushed - not unearned exactly, but tidier than life tends to be. Some supporting characters remain sketches rather than people. And the point-of-view shifts can feel slightly awkward, like the book can't quite decide how close to get to its characters.
But these are quibbles. For a debut novel tackling difficult material, Spiro shows real skill. The final third delivers emotionally in ways that justify the slow burn. When Lindsey and Georgie finally confront what they've buried, it doesn't feel like plot mechanics - it feels like two people who've carried something too long finally putting it down.
Rating: 4.0/5 ⭐
Perfect for: Readers who don't mind slow builds with big payoffs, anyone interested in class dynamics and female friendship, those who appreciate books that take trauma seriously without exploiting it.
Skip if: You need fast pacing throughout, prefer to avoid sexual assault themes, or tidy endings frustrate you.
