Elin Hilderbrand is known as the “Queen of Beach Reads,” and for twenty years her annual summer novel has been a ritual for millions of readers. Swan Song (2024) is her final Nantucket novel — the last book in a career that defined the genre — and it is a fitting farewell: a mystery, a family drama, and a love letter to the island she has written about for two decades. This is a full book report.
About the author
Elin Hilderbrand was born in 1969 in Collegeville, Pennsylvania. She studied creative writing at Johns Hopkins University and earned an MFA from the University of Iowa. She moved to Nantucket in 1993, and the island became the setting for nearly all of her novels. Her first book, Summer People (2003), began a run of more than thirty novels, most of them set on Nantucket, including The Blue Bistro, The Perfect Couple (adapted into a Netflix series in 2024), and the Winter Street series. She has sold more than 20 million books. In 2023 she announced that Swan Song would be her last Nantucket novel — she has said she wants to spend her summers with her family instead of writing about the island. She has also written two books with her son, Dawson Hilderbrand Reed, under the pen name Elin Hilderbrand.
The setup
It is the summer of 2024 on Nantucket, and Chief of Police Ed Kapenash is counting down the days to retirement. He has been the island’s top cop for twenty years, and he wants to go out clean. But the summer brings a case that will not let him go quietly.
A young woman named Coco is missing. She was last seen at a party at the Richardson house — a $30 million glass-and-wood mansion on the beach, owned by the Richardson family, who are new money from the tech world. The Richardsons are the kind of family that buys an island landmark and rebuilds it: flashy, secretive, and full of tension. Coco was their au pair, and her disappearance tears the family open.
As Kapenash investigates, he is joined by his partner in the department, and the case pulls them into the Richardsons’ world of money, secrets, and lies.
The characters
Ed Kapenash is the anchor of the book — a good man, tired, counting down to retirement, and determined to solve one last case. He is the reader’s guide through the island and the investigation. His quiet decency is the book’s moral center.
The Richardson family are the suspects: the patriarch, a tech billionaire who made his fortune and bought his way onto the island; his wife, who is trying to hold the family together; and their children, who are spoiled, resentful, and hiding things. Hilderbrand is good at making rich families feel real — their money is a character in itself.
Coco is the missing au pair — young, beautiful, and mysterious. The book is partly about who she really was, and the answer is more complicated than anyone expects.
The supporting cast is pure Hilderbrand: island locals, summer people, restaurant owners, and the small-town network that makes Nantucket feel like a village. Everyone knows everyone, and everyone has an opinion.
The plot, without spoilers
The investigation into Coco’s disappearance unfolds over the summer, with Kapenash interviewing the Richardsons and their circle. The family’s secrets come out one by one: an affair, a financial scandal, a rivalry between siblings. The more Kapenash learns, the less clear it is whether Coco ran away, was taken, or was hurt by someone she trusted.
Meanwhile, the book follows the Richardsons’ summer — the parties, the tensions, the slow unraveling. Hilderbrand weaves the mystery through the family drama, and the two strands tighten together toward the end. The climax reveals what happened to Coco, and the answer is both surprising and sad — a resolution that fits the book’s themes of money, family, and the cost of keeping secrets.
Themes
Money and class. The Richardsons are new money on an island of old money, and the book is sharp about the difference. Hilderbrand has spent twenty years writing about the rich, and she knows exactly how they work.
Family secrets. The book is about what families hide from each other — and what they hide from themselves. Every character is keeping something.
Endings and goodbyes. Kapenash is retiring. Hilderbrand is leaving the island behind. The book is suffused with the feeling of an ending — of a career, a season, a way of life.
Small-town justice. The island is a community where everyone knows everyone, and the book asks whether that helps or hurts the search for truth.
Writing style
Hilderbrand writes in a warm, readable style with short chapters and a rotating point of view. Her books are easy to sink into — the prose is never showy, but it is precise, and she has a gift for making you care about people quickly. She is also a master of the summer setting: the food, the beaches, the parties, the weather. Reading her is like spending a summer on Nantucket, and Swan Song is her most Nantucket book of all — a farewell tour of the island she made famous.
What works
- The mystery. It is a real page-turner, with a genuinely surprising resolution.
- The setting. Hilderbrand’s Nantucket is vivid and specific — you can smell the ocean.
- Kapenash. A warm, tired, decent protagonist who is easy to root for.
- The farewell quality. Knowing this is the last Nantucket novel gives the whole book a bittersweet weight.
What does not work
- The Richardsons can be exhausting — rich people behaving badly is the point, but it can wear thin.
- Some readers will find the pacing slow in the middle, as the family drama takes over from the mystery.
- If you have never read Hilderbrand, some of the island references will go over your head — though the book works fine as a standalone.
Who should read it
Read it if you love beach reads, family dramas, or mysteries with heart. Read it if you have followed Hilderbrand’s career and want the farewell. Read it if you liked The Perfect Couple on Netflix. It is the perfect summer book — which is fitting, since it is the last one.
Verdict
4 out of 5. A warm, satisfying farewell from the Queen of Beach Reads. It is not Hilderbrand’s deepest book, but it is one of her most complete — a mystery, a family saga, and a love letter to Nantucket, all in one. If you have ever spent a summer with her books, this one will make you a little sad that it is over.
A closer look: Nantucket in Hilderbrand’s fiction
To understand what Swan Song means to Hilderbrand’s readers, you have to understand what Nantucket means to her books. For more than twenty years, the island has been her only real setting — a small, windswept, impossibly expensive place thirty miles off the coast of Massachusetts, where summer people and year-rounders live side by side and everyone knows everyone’s business. Her novels are essentially a long chronicle of the island: the restaurants, the beaches, the houses, the families who have been there for generations and the ones who just arrived. Swan Song is full of farewells to all of it — the places and people her readers have come to know book after book. Longtime fans will recognize the texture of the island in every chapter, and that is exactly the point. The book is a goodbye, and it is written with the affection of someone who knows she will miss the place. For readers, it works the same way: a last summer on an island they have visited in books for two decades, with a mystery to keep the pages turning and a melancholy that settles in by the final chapter.
