Detroit hums beneath the smokestacks of 1927, and Ruta Sepetys returns to her birthplace with a story hiding in plain sight for a century. A Fortune of Sand by Ruta Sepetys moves the Lithuanian-American novelist away from the European stages of her earlier work and plants her firmly in the Motor City, swapping deportation trains and refugee ships for hidden speakeasies, glass dynasties, and a women’s arts residency that begins to feel less like sanctuary and more like a snare.
The Setup: A Velvet Brat With Bigger Plans
Marjorie Lennox is the youngest of four siblings born into a family that built its fortune on automotive glass. Her father runs the dynasty like a feudal lord, her mother drifts through tennis and lovers, and her older siblings each carry their own variety of damage. Marjorie sews her own clothes, talks to trees, and quotes poetry at police officers. So when she stumbles across a brochure for an invitation-only artists’ residency funded by the elusive Charles Bonafante, the chance to escape Grosse Pointe feels like deliverance.
The residency takes her to the Nightingale, a handsome stone building with ironwork, locked doors, and a clipboard-wielding overseer named Dock. Curfew is nine. The lease has fine print no one bothers to read. The other residents include a furniture designer obsessed with molded plywood and a glamorous painter who hears screaming through the walls. Marjorie wants to believe in Bonafante’s vision. She also wants to believe in Bonafante himself, which complicates her judgment about everything else.
What Sepetys Does Beautifully
Sepetys is a researcher first, and a decade of digging through Detroit Police archives, Detroit Free Press clippings, and Grosse Pointe Historical Society files comes through on every page. The 1925 Detroit Institute of Arts jewel heist, in which a young woman from Grosse Pointe was named as accomplice and a young man became the target of blackmail, is real history almost no one remembers. Sepetys excavates it without lecturing, threading the real crime through the fictional Lennox family in a way that feels earned rather than imposed.
A few elements stand out as the book’s strongest:
- A specific, unsanitized Detroit. Sooty smokestacks, Canadian Club lights blinking across the river, the Pontchartrain Hotel, the Detroit Yacht Club, and the Statler. Detroit’s immigrant quilt of Scots, Irish, German, Jewish, Italian, Polish, Lebanese, and Greek communities is treated as fabric, not flavor.
- Marjorie’s voice. She catalogs people by their feet. She is funny, observant, sometimes maddeningly literal, and occasionally sharper than anyone around her wants to admit.
- A genuinely uncomfortable historical premise. The book quietly indicts how often “embarrassing” women were committed to asylums like Eloise by husbands and fathers in this era. It is a quieter horror than a body in the library, and it lands harder.
- The supporting women. Bernice the furniture maker and Ivy the painter feel like specific people, not types, and the friendships among the residents power the book’s emotional center.
The prose stays close to Sepetys’s signature mode. Short sentences, dialogue that pings off the page, and small sensory observations that land sideways. There is an unusual rhythm to her brief chapters, many of them ending on a beat that makes you turn the page reflexively.
Where It Stumbles
Calibration matters in a book like this, and A Fortune of Sand by Ruta Sepetys does not always get it right. The Lennox siblings are vivid in early scenes (Chet with her typewritten mock obituaries, Graham with his eye patch and shrugging affection) but they sometimes shade into eccentricity for its own sake. The witticisms can grow weary, particularly in the dinner-table set pieces where each sibling delivers a line and exits.
Charles Bonafante is the book’s biggest puzzle, and the puzzle is partly a problem. Sepetys wants him to function as both romantic temptation and unknowable patron, which is workable, but his actual presence on the page is so sparing that when he does enter, every line carries too much weight. Readers expecting a fully drawn love interest may find themselves circling a silhouette.
The pacing is uneven. The Nightingale chapters move with real tension, and the back half stitches together the heist, the residency, and the family politics with skill. The opening, though, takes its time setting up the Lennox household, and a few subplots feel like they were either trimmed late or seeded for a sequel.
A Familiar Voice in a New Setting
Anyone who has read Salt to the Sea or Between Shades of Gray knows Sepetys writes about women caught in the machinery of larger systems. Here she keeps that interest but trades the European tragedies of her earlier work for an American one, less brutal in scale, just as targeted in intent. The same author who once gave voice to deportees and refugees now turns her attention to debutantes, designers, and the wives quietly disappeared by their own families. Readers who came to Sepetys for the weight of The Fountains of Silence or I Must Betray You should expect a lighter, glassier register, though A Fortune of Sand by Ruta Sepetys still carries the moral seriousness that defines her catalog.
Who Will Love It
A Fortune of Sand by Ruta Sepetys suits readers who:
- Enjoy historical mysteries grounded in real archival material rather than invented intrigue
- Like 1920s atmosphere served with bootleggers, broken families, and underestimated women
- Want a heroine more observant than she lets on
- Don’t mind a slow first quarter if the back half pays off
It will frustrate readers who want their thrillers tighter, their love interests fully present, and their endings unambiguous. The conclusion is satisfying in the way Sepetys endings usually are: open enough to feel real, closed enough to feel chosen.
If You Enjoyed This, Try
- The Lions of Fifth Avenue by Fiona Davis, for another novel built around a real, half-forgotten historical art crime
- The Diviners by Libba Bray, for 1920s atmosphere, eccentric heroines, and a sense of menace under the glitter
- The Stolen Queen by Fiona Davis, for women navigating restrictive institutions
- The Mystery of Mrs. Christie by Marie Benedict, for a comparable mix of biographical fact and structured fiction
- The Magnificent Lives of Marjorie Post by Allison Pataki, for another portrait of a wealthy American heiress finding her own footing
Final Word
A Fortune of Sand by Ruta Sepetys is not the author’s tightest book, but it may be her most personal. Her grandfathers worked for Ford. Her father owned a Detroit design firm. The book wears its love for Detroit openly. That affection, more than the mystery or the romance, is the foundation holding the novel together. Even when the prose stumbles, the love does not, and it is reason enough to follow Marjorie Lennox through the smoke and the glass and back out again.
