Elin Hilderbrand is basically the queen of Nantucket summer fiction, and I've read enough of her books to know what I'm signing up for: sun, secrets, and somebody's marriage falling apart over lobster rolls. But Castaways hit different from her usual beach reads, and I wasn't entirely prepared for that. I got a similar 'this is heavier than the cover suggests' feeling from Barefoot, another Hilderbrand that trades fluff for real emotional weight.
Here's the setup: Greg and Tess MacAvoy drown in a sailing accident on their wedding anniversary. They leave behind two little kids and three couples who were their closest friends. The rest of the book is these six people - already messy, already harboring grudges and attractions and guilt - unraveling as they grieve and as secrets about the MacAvoys' marriage start surfacing. It's not a whodunit exactly, but there's this persistent question of what really happened on that boat, and Hilderbrand lets it simmer under everything.
When Friendship Is the Thing That Drowns
What got me was how accurately this book captures the way adult friendships are held together by habit and proximity as much as actual love. Each couple gets their own perspective - the chief of police and his wife, the high school English teacher dealing with her own crumbling marriage, the perpetually single guy orbiting the group. And Hilderbrand does this thing where she reveals each person's private relationship with Greg or Tess, and you realize nobody in this friend group actually knew each other as well as they thought. The affairs, the resentments, the financial entanglements - it's all very "dinner party where everyone's performing." I've been to those dinner parties. We've all been to those dinner parties.
The structure works surprisingly well for interrupted listening. Each chapter focuses on a different character's POV, so when Sophie woke up from her nap screaming about her blanket being "wrong" (it was the same blanket, Sophie), I could pick right back up without losing the thread. Survived 47 pauses and still made sense. That said, 13 hours is a commitment. This is not a quick nap-time finish. It took me almost two weeks, and there were stretches in the middle - particularly around the third couple's marital problems - where I felt like Hilderbrand was stirring the same pot without adding new ingredients.
Katie Hale: Pleasant Voice, Questionable Pronunciation
Okay, so here's where I have to be honest. Katie Hale has a genuinely warm voice and she does give each character their own sound, which matters a LOT in a book with this many POV characters. The chief's wife sounds different from the schoolteacher, and you can tell who's talking without checking. That's not nothing in a six-person ensemble.
But. The mispronunciations. I don't know what happened in the recording booth, but basic terms get mangled in ways that yanked me right out of the story. I've listened to other Hilderbrand audiobooks narrated by Christina Delaney and the difference is noticeable - Delaney has this effortless Nantucket-summer vibe that Hale doesn't quite nail. Delaney does such a good job that I even forgave the weaker plotting in Summer of '79 just because listening to her felt like a vacation. Hale is perfectly fine. She's just not the narrator who makes you forget you're listening to an audiobook.
Also, there are these musical interludes between sections that are... a choice. They felt jarring and weirdly dated, like someone added a screensaver soundtrack between chapters. I could've done without them entirely.
The Grief Part No One Warned Me About
Here's what I didn't expect: this book actually nails grief. Not the performative kind, but the ugly, selfish kind where you're mourning your friend and simultaneously relieved their marriage problems aren't your problem anymore, and then feeling guilty about being relieved. The way each character processes the MacAvoys' death reveals more about their own fears than their actual loss. As a mom of small kids, the subplot about what happens to Greg and Tess's children - who takes them, who should take them, the quiet power struggle over it - that part sat heavy with me. I was listening in my car in the garage (don't judge me, that car time is sacred) and I had to just sit there for a minute.
Not groundbreaking, but sometimes you don't need groundbreaking. You need a book that understands how complicated it is to love your friends and also kind of resent them, and what happens when the person holding the group together is suddenly gone.
Who Gets the Last Invite
If you love Hilderbrand's other stuff, this is meatier than her typical summer romp - more grief, less beach, still plenty of Nantucket atmosphere. It's actually more in line with the family drama side of her catalog than the breezy stuff people expect. If you're coming in fresh, know that it's a slow burn with a LOT of characters and relationship dynamics. My book club would love this (if I ever have time for book club again). Skip it if mispronunciations are a dealbreaker for you in audio, or if you want something lighter. Made me cry at school pickup. Worth it though.
