The Girls Left Behind by Emily Gunnis Review: A Gripping Multi-Timeline Mystery Thriller

Emily Gunnis's The Girls Left Behind is a mystery thriller that weaves triple timelines — World War Two, the 1970s/80s, and the 2000s — around the disappearance of girls from a notorious children's home called Morgate House, anchored by the determined Superintendent Jo Hamilton as she races to uncover decades of buried wrongs before her retirement.

LuvemBooks Verdict

Best for

Readers who enjoy character-driven British crime fiction with a strong historical dimension — particularly those drawn to stories of institutional injustice, wronged women, and multi-generational mystery, and who already love Emily Gunnis's debut, The Girl in the Letter.

Worth it if

You're willing to invest in a structurally ambitious triple-timeline thriller where the complexity pays off in a genuinely surprising and emotionally satisfying ending.

Skip if

You prefer tightly focused, single-perspective narratives, or are sensitive to substantively dark subject matter including child abuse, institutional cover-up, and the deaths of children.

Readers on NetGalley consistently praised Gunnis's command of the triple-timeline structure and her three central female characters, with one calling the ending "brilliant" and genuinely unexpected. Reviewer Sandra Danby at sandradanby.com acknowledged the ambition of the approach while noting it is "a complicated mixture to handle" with "a lot of personalities and twists to hang on to," and goodbadandunread.com found the wartime strand less engaging than the more recent timelines, awarding the novel a Grade B overall.

What Works & What Doesn't

What Works
  • Triple-timeline structure — spanning World War Two, the 1970s/80s, and the 2000s — is praised by multiple readers as cleverly handled and effective at sustaining tension
  • Three central female characters, including retiring Superintendent Jo Hamilton and sisters Holly and Daisy, are consistently described as strong and well-drawn
  • The ending drew particular acclaim from readers, who found it genuinely surprising and satisfying
  • Continues the tradition established by The Girl in the Letter, making it a natural next read for existing fans of Gunnis's historical crime fiction
  • Available in multiple formats including Kindle and audiobook, with the audiobook narrated by Clare Corbett to strong reader response
What Doesn't
  • The three-timeline structure and large cast of characters create significant complexity that some readers may find demanding, particularly early in the novel
  • The subject matter — child abuse, institutional cover-up, and the deaths of children at Morgate House — is substantively dark and not suited to all readers
A layered and emotionally charged mystery thriller, The Girls Left Behind confirms Emily Gunnis as a storyteller with a firm command of suspense across time.

The Girls Left Behind: A home for troubled children; a lifetime of hidden secrets. The gripping, moving novel from the bestselling author by Emily Gunnis front cover
The Girls Left Behind centres on Superintendent Jo Hamilton, who is days from retirement from Sussex Police when the discovery of a young woman's bones draws her back to a case she first worked as a WPC in the 1970s: the disappearance of a teenage girl from Morgate House, a notorious local children's home, where another young resident had died in suspicious circumstances not long before. Convinced that reopening the hushed-up wrongs of the past is the only path to truth, Jo sets out to find the missing girl's sister — a search the novel's publisher describes as leading "disturbingly close to home." The story moves across three distinct periods: World War Two, the 1970s and 1980s, and the early 2000s, tracking the fates of multiple characters whose lives intersect around Morgate House and the secrets it kept. One reviewer on NetGalley noted the novel touches on themes of sisterly love, friendship, deceit, child abuse, guilt, and determination — a broad emotional and moral canvas stretched across its multi-generational structure.
masterfully wove together the stories of these three strong female characters

The Author's Background and Place in the Genre

Gunnis — who previously worked in TV drama and lives in Brighton — is the daughter of the late bestselling novelist Penny Vincenzi, and has spoken openly about the influence her mother's storytelling had on her own path to writing. Her debut, The Girl in the Letter, established her reputation for weaving historical injustice into propulsive contemporary fiction; The Girls Left Behind continues in that tradition, again placing institutional wrongdoing and the suffering of vulnerable girls at the heart of its plot. Published by Headline Review, the novel is positioned squarely within the tradition of British women's detective and historical thriller fiction, a genre that rewards writers who can balance emotional authenticity with carefully timed revelations — both of which Gunnis demonstrates here.

Strengths: Plotting, Pacing, and Character

Reader responses gathered on NetGalley converge on several consistent strengths. Multiple reviewers single out Gunnis's command of the triple-timeline structure, with one noting that "the different timelines really worked to keep the tension alive" and another describing the storyline and timeline changes as "cleverly done." The three central female characters — Jo Hamilton, and the sisters Holly and Daisy, who ended up at Morgate House — are repeatedly described as strong and well-differentiated. One NetGalley reviewer observed that Gunnis "masterfully wove together the stories of these three strong female characters," and praised an ending described as "brilliant" and genuinely surprising. The audiobook edition, narrated by Clare Corbett, also drew praise on NetGalley, where one reviewer called the novel "well plotted, fast paced" with "several twists."

Genuine Limitations and Readers to Consider

The novel's ambition is also its primary challenge. Handling three separate timelines — World War Two, the 1970s/80s, and the 2000s — alongside a large cast of interconnected characters is, as one reviewer at sandradanby.com put it plainly, "a complicated mixture to handle" with "a lot of personalities and twists to hang on to." Readers who prefer a tightly focused single perspective or a more linear narrative may find the structural complexity demanding, particularly in the novel's earlier sections before the threads begin to converge. The subject matter — child abuse, institutional cover-up, and generational trauma — is substantively dark, and while those themes are central to the story's power, readers sensitive to depictions of the mistreatment of children should enter with that expectation clearly set.

Who This Book Is For

The Girls Left Behind is designed for readers who enjoy character-driven British crime fiction with a strong historical dimension — those who appreciate novels that use the past not merely as backdrop but as the engine of present-day reckoning. Fans of Gunnis's debut, The Girl in the Letter, will find familiar DNA here: institutional injustice, wronged women, and a structure that builds steadily toward a payoff that several reviewers found genuinely earned. For those new to Gunnis, this novel functions equally well as an entry point. One NetGalley reviewer, encountering her work for the first time, concluded simply: "It is the first book I have read by Emily Gunnis but it won't be my last."
