The Last Time We Drowned by Saratoga Schaefer Review: A Razor-Sharp Locked-Yacht Thriller

Published June 2, 2026, by Cosmo Reads, The Last Time We Drowned is Saratoga Schaefer's third novel — a psychological thriller set aboard a luxury yacht — and an instant USA Today bestseller. It follows Charlie Engles, a bookstagrammer who accepts a job that drops her into a world of wealthy social-media influencers, only for the voyage to spiral into a locked-room mystery at sea. Blending social commentary, horror undertones, and a deeply flawed but compelling protagonist, the novel has drawn strong praise from Booklist and Cosmopolitan, and stands as a confident genre evolution for an author already known for Serial Killer Support Group and Trad Wife.

LuvemBooks Verdict

Best for

Readers who love character-driven psychological thrillers with a social-media edge — especially fans of Schaefer's earlier work or anyone who wants a locked-room mystery that trades glossy influencer aesthetics for genuine dread and a queer, deeply flawed protagonist at its centre.

Worth it if

You're drawn to thrillers that use a propulsive, high-concept premise — six influencers, one luxury yacht, one very bad situation — as a vehicle for sharp social commentary, horror-inflected atmosphere, and a second half that pays off a patient first-half setup with real momentum.

Skip if

Readers who need relentless, breakneck pacing from the very first page may lose patience with the novel's more deliberate, atmosphere-building first half before the thriller machinery fully locks in.

Cosmopolitan, whose Cosmo Reads imprint published the novel, called it "an incredible, one-of-a-kind psychological thriller that you won't be able to put down until the very last page," while Macabre Daily noted that Schaefer blends elements of the ghost story, locked-room mystery, social commentary, and psychological thriller into a single multilevel package. Crime Spree Magazine characterised it as "a solid psychological thriller set against an opulent, glittering backdrop" that begins as a slow burn before accelerating in its second half, and Fangirlish praised it as "a fast-paced, smart psychological thriller that never goes where you expect."

What Works & What Doesn't

What Works
  • An instant USA Today bestseller with strong critical praise from Booklist and Cosmopolitan, signaling broad commercial and editorial appeal
  • A deeply flawed, queer protagonist in Charlie Engles gives the thriller emotional texture beyond genre conventions
  • Booklist cites snappy dialogue, biting prose, and a deeply felt sense of place as standout craft elements
  • The locked-yacht, locked-room structure blends classic mystery with sharp social commentary on influencer culture and the dark side of wealth
  • Schaefer's horror-inflected tension, carried over from earlier work, gives the thriller an unsettling depth that readers report exceeds expectations
What Doesn't
  • The more gradual, atmosphere-building first half may test readers seeking immediate, relentless pace from page one
  • Readers unfamiliar with Schaefer's prior novels may need time to calibrate to a thriller that layers horror sensibility into a mystery framework
The Last Time We Drowned is the rare thriller that earns both its beach-read credentials and its darker ambitions in equal measure.

What the Book Is: A Locked-Yacht Mystery for the Influencer Age

The Last Time We Drowned centers on Charlie Engles, a bookstagrammer who accepts what initially appears to be a lucrative opportunity: a spot aboard a luxury yacht headed for Ligia Island, surrounded by a coterie of high-profile social-media influencers. The novel's premise is established with brisk urgency; as an excerpted passage published by Cosmopolitan reads, one character snaps at Charlie, "I don't like wasting time. You're here, your shit is here, my boat is in the harbor. Ligia Island is forty minutes away. You said you need the money. Why wait? You in, or what?" That snap-cut energy carries the setup forward: six influencers, one vessel, and a situation that quickly transforms from glamorous retreat into something far more menacing. The locked-room-at-sea structure — a scenario with deep roots in classic mystery fiction — gives Schaefer a pressure cooker in which to stage their brand of escalating dread.
an incredible, one-of-a-kind psychological thriller that you won't be able to put down until the very last page.

Significance: Agatha Christie Meets the Instagram Age

Ashley Winstead, the USA Today-bestselling author of This Book Will Bury Me, has described the novel as delivering "Agatha Christie for the Instagram age in this deliciously soapy saga," pointing to a core tension that gives the book its cultural bite: the collision of curated online performance with genuine mortal stakes. Schaefer is not simply using influencer culture as a set dressing; the dark underbelly of wealth and the mechanics of "mean-girl" social hierarchies are, per the book's reception, integral to its architecture. This positions The Last Time We Drowned within a growing strand of thriller fiction that treats social media not merely as backdrop but as a system of power with real, dangerous consequences — a thematic territory Schaefer had already explored in Trad Wife, their previous novel.

Craft and Strengths: Pace, Prose, and a Complicated Protagonist

critics described the novel as "an addictive, page-turning thriller with snappy dialogue, biting prose, a deeply felt sense of place, and an incredibly complicated, flawed protagonist with a big heart" — a characterization that isolates several distinct craft virtues at once. Charlie Engles is positioned as an outsider who does not naturally belong among the influencer class she's been dropped into, and readers and critics responding on NetGalley noted that Schaefer structures the novel deliberately: a more measured first half builds character and setting, while the second half accelerates into fast-paced twists and unexpected character decisions. Cosmopolitan called it "an incredible, one-of-a-kind psychological thriller that you won't be able to put down until the very last page." The novel also carries what one NetGalley reader described as a "deeper, more layered" quality than the genre typically promises — a compliment that speaks to Schaefer's ability to make the psychological machinery feel earned rather than mechanical.

Genre Blend: Horror Undertones in a Thriller Frame

A consistent thread in the novel's early reception is the presence of horror influences bleeding through the mystery-thriller frame. Reviewers at NetGalley and Cape & Tights, who had access to advance copies, noted that while The Last Time We Drowned is firmly a mystery thriller, Schaefer's signature "creeping sense of tension and dread" — honed across Serial Killer Support Group and the body-horror inflections of Trad Wife — seeps into this new setting. Cape & Tights characterized the book as a "multilevel thriller" that blends elements of the ghost story and the locked-room mystery with psychological suspense and social commentary. This genre layering is part of what distinguishes the book from a more conventional beach thriller: readers who arrived expecting something light and frothy, per multiple advance responses, found the darkness ran considerably deeper than the glittering yacht premise suggested.

Who It's For and Where It Stretches

The Last Time We Drowned is well suited to readers drawn to character-driven psychological thrillers with literary ambitions — particularly those who found Schaefer's earlier work compelling and are ready for them to operate within a more plot-driven mystery structure. The queer identity of the protagonist is noted in the author's own framing of the book as "compelling, queer, dark-and-deep," adding a dimension of representation that distinguishes Charlie further from the thriller genre's more conventional protagonists. Readers who prefer pure-speed plotting with minimal atmospheric groundwork may find the novel's more deliberate first half requires patience before the thriller mechanics fully engage. But for readers who prize a "deeply felt sense of place" —critical reception's phrase — and a protagonist whose flaws feel genuinely earned rather than decorative, Schaefer's third novel makes a strong case that their range continues to expand with each book.
