Hollow City Review

Hollow City review: a sequel that trades enclosed mystery for wartime momentum

This Hollow City review argues that Ransom Riggs's second Miss Peregrine novel succeeds because it understands what a sequel must change. The first book won readers through its strange boarding-school premise, its melancholy old photographs, and the eerie comfort of children suspended outside ordinary time. Hollow City cannot simply repeat that architecture. Instead, it sends its characters outward, strips away some of the first novel's protective enclosure, and asks whether the series can remain emotionally engaging once wonder has to survive exposure, pursuit, and the pressure of a larger world.

That shift is mostly a good one. Hollow City is more obviously an adventure novel than Miss Peregrine's Home for Peculiar Children, but it does not abandon the gothic-horror identity that made the series distinct. Riggs keeps the unsettling photographs, the melancholy strangeness, and the sense that childhood here is always shadowed by damage. What changes is the ratio. Instead of a puzzle box about a hidden refuge, the sequel becomes a chase story through bomb-scarred spaces, temporary shelters, dangerous alliances, and expanding supernatural conflict.

The central judgment is simple: Hollow City is an effective, sometimes uneven sequel that deepens the series by making its found-family stakes more urgent than its lore. Readers who want a faster, darker, more outward-moving continuation will likely find it satisfying. Readers who mainly loved the first book for its singular atmosphere of discovery may notice the strain that comes when a moody premise has to become an ongoing saga.

Why Hollow City works better as a sequel than as a stand-alone novel

The first thing to say clearly is that Hollow City is not built for newcomers. It starts in motion and expects readers to arrive carrying emotional investment, remembered rules, and affection for the children's fragile group identity. That dependence is not a flaw in itself. Sequels often go wrong when they pause too often to re-explain their own mythology. Riggs avoids that, and the result is a book with better immediate momentum than many second installments.

More importantly, he recognizes that the sequel's central job is not only to enlarge the map. It is to test the first book's core claims. In Miss Peregrine's Home for Peculiar Children, the question is whether a hidden sanctuary can exist at all. In Hollow City, the question becomes what happens when sanctuary fails to hold. That is a far stronger dramatic engine. The children are no longer primarily being introduced to the reader; they are being pressured into decisions, loyalties, and risks that reveal which bonds are durable and which comforts belonged mostly to the closed conditions of the first novel.

This is where the book earns its place on the site's young adult shelf. It is not merely a continuation of plot. It is a continuation of adolescence under harsher conditions. The peculiar children are forced to move from an identity built around belonging toward one built around action and mutual dependence. That is a meaningful maturation of the series. The novel still offers monsters, powers, strange settings, and cliff-edge suspense, but it also becomes more interested in what leadership, courage, jealousy, trust, and fear look like inside a group of young people who cannot simply retreat to a safe room and wait for adults to fix things.

At the same time, the book remains legibly middle-volume in shape. It broadens the world, escalates danger, and carries several threads forward without always resolving them into a fully self-sufficient dramatic arc. Some readers will experience that as thrilling propulsion. Others will feel the scaffolding. Both responses are fair. Hollow City is best when read as the book that turns a successful premise into an actual series, not as a perfectly sealed novel.

The old-photograph gothic atmosphere still matters, even in a faster book

Riggs's real signature has never been plot alone. It is the combination of fantasy narrative with found photography, antique textures, and a slightly mournful sense that the past is peering through damaged paper. A sequel like Hollow City could easily have lost that identity by leaning too hard into action. What saves the book is that Riggs still knows atmosphere is part of the argument, not just decoration.

The photographs remain crucial because they make the peculiar world feel archival rather than invented from scratch. They suggest evidence, fragments, and leftover lives. That matters especially in a sequel, where readers no longer need persuasion that the strange children exist. What they need is a reason to keep feeling the strange children as uncanny. The vintage images continue to provide that. They hold the series in a gothic register even when the plot begins to operate more like a wartime pursuit fantasy.

The wartime backdrop is especially effective in this respect. London under bombardment, ruined buildings, and a general sense of historical emergency give Hollow City a denser mood than the first novel's isolated-island mystery. Riggs is good at making crumbling streets and precarious shelters feel spiritually compatible with his monsters and peculiars. The world of the novel becomes more mobile, but not more generic. Its fantasy still arrives through dust, damage, old rooms, hidden passages, and the feeling that safety has always been provisional.

That is why the book also belongs, at least in tonal conversation, with readers browsing fantasy who like dark atmosphere more than elaborate system-building. Riggs is not a maximalist worldbuilder in the mode of epic fantasy. He is better at curating a feeling: abandoned elegance, threatened innocence, period detail, and dread that remains accessible to younger readers without becoming toothless. When Hollow City is at its best, it turns movement itself into mood. Every new place seems temporary, storied, and at risk of becoming a trap.

Readers expecting pure horror should calibrate accordingly. The novel absolutely uses fantasy-horror imagery, monstrous pursuit, and children in danger, but it is still primarily a crossover adventure fantasy rather than a book designed to terrorize. The eeriness is steady; the brutality is moderated by the series' readability. That balance is one reason the book has broad appeal, but it also explains why hardened horror readers may find it more atmospheric than frightening.

Jacob, the ensemble, and the stronger found-family core

If the first novel's greatest asset was premise, this sequel's greatest asset is group pressure. Hollow City becomes more interesting as the children's relationships matter more than the simple novelty of their abilities. Riggs understands that a series cannot survive on eccentric powers and spooky visuals forever. It has to make readers care about who protects whom, who falters under stress, who feels left behind, and how loyalty changes when danger stops being abstract.

Jacob is a more functional protagonist here than in the opening book because the sequel gives him less time to remain merely reactive. He is still a gateway figure, still discovering the scale of the world he has entered, but Hollow City forces him to translate attachment into action. That is good sequel craft. A second volume should not just repeat the emotional work of initiation. It should show whether initiation actually changed the character. Riggs makes Jacob more credible by embedding him in choices rather than only revelations.

The ensemble also benefits from the book's travel structure. When a cast is stuck in one strange institution, the story can lean heavily on archetype and charm. Once that cast is moving through danger, hidden insecurities and competing instincts have more room to surface. Hollow City does not transform every supporting character into a fully independent psychological study, but it does make the group feel more interdependent and more vulnerable. That goes a long way toward giving the novel real emotional traction.

This is also where the found-family theme becomes most persuasive. The children are peculiar, but the book's emotional logic is recognizably human: they are bound by chosen loyalty, by shared exile, and by the knowledge that ordinary systems do not have a place prepared for them. Readers who are drawn to fantasy partly because it builds intense surrogate-family structures will likely respond to this aspect of the novel. The series remains youth-facing, but it is serious enough to understand that belonging is not soft. Belonging becomes demanding when protection fails and everyone has to keep moving anyway.

For readers who prize emotional sharpness in younger-skewing speculative fiction, this is the clearest reason to keep going beyond the first book. Hollow City may be broader in scope, but it is also more dependent on trust, fear, and group cohesion. That makes it less pristine than the opener, yet more involving in a durable way.

Pacing, episodic structure, and where the middle-book strain shows

The biggest caution with Hollow City is pacing. Not slow pacing exactly, because the novel has plenty of incident, but uneven pacing. Riggs often moves well at the scene level. There is pursuit, concealment, revelation, and the recurring anxiety that a temporary refuge will not remain safe for long. The problem is that these scenes do not always accumulate with equal force. The novel can feel episodic, as if it is repeatedly generating strong local tension while postponing a deeper sense of arrival.

That quality is very common in second books. A sequel must widen the world, reposition characters, thicken the threat, and prepare the next stage of the series. Often that means certain passages function more as transfer points than as revelations. Hollow City is not free of that burden. You can feel the machinery at times. Some sections are memorable because of atmosphere or peril rather than because they decisively alter the book's larger understanding of itself.

Still, Riggs does enough to keep the episodic structure from collapsing into emptiness. First, the emotional thread remains clear: the children need each other, need safety, and need some path forward in a world that is increasingly hostile to them. Second, the novel rarely loses its tonal identity. Even when the plot is moving from one stop to the next, the wartime-gothic mood keeps the book coherent. Third, the photographs and visual imagination make many transitions feel less disposable than they might in a more generic YA fantasy sequel.

This is the section where reader-fit matters most. If you read sequels mainly for acceleration, higher stakes, and the pleasure of remaining in a world you already like, Hollow City may work very well. If you need every installment to have the shaped finality of a stand-alone novel, you may find it comparatively ragged. The book is better at sustaining intrigue and emotional attachment than at delivering perfect structural elegance.

That does not mean the pacing complaints are trivial. They are real. But they are also part of what the novel is trying to do: shift a concept-driven debut into a mobile series without flattening its mood into franchise autopilot. A somewhat lumpy sequel with a strong identity is more valuable here than a smoother one that forgets what made its world unusual in the first place.

Violence, trauma, and how dark the book really gets

Because the series is often discussed in terms of eerie photographs and whimsical peculiar powers, it is worth being plain about the darker material. Hollow City carries sustained menace. Children are hunted. Violence has consequences. The story lives near trauma, displacement, bodily threat, and a recurring sense that innocence is something these characters must actively defend rather than naturally possess.

Even so, Riggs is writing for a broad crossover audience, and he knows how to keep the darkness readable. The book is not graphic in the way adult horror often is, nor is it psychologically punishing in the register of the bleakest dystopian YA. Instead, it uses fear as a constant climate. The sense of danger matters more than explicit detail. That makes the novel approachable for many teen readers while still giving it enough edge to avoid feeling sanitized.

The historical setting helps here too. War is not only a cool backdrop or a decorative landscape of ruins. It lends the novel moral and emotional weight because it places the peculiar children's private crisis against a larger world already fractured by violence. Riggs does not turn the book into historical realism, but he benefits from the way wartime imagery naturally intensifies themes of evacuation, endangered childhood, and improvised kinship.

Readers sensitive to children in peril should know that this is not just a spooky-curiosity sequel. The book wants the reader to feel that the children's strangeness makes them both wondrous and vulnerable. That tension is central to the series' appeal, but it is also where some readers will decide the tone is harsher than they want. Compared with a grief-centered but more intimate crossover novel like A Monster Calls, Riggs is less psychologically concentrated and more plot-driven. Compared with a philosophically denser sequel like The Subtle Knife, he is more visually curated and less conceptually severe. Hollow City occupies its own middle space: dark enough to feel perilous, accessible enough to remain a page-turner.

Who should read Hollow City, and who may like the first book more

The best audience for Hollow City is readers who finished the first novel wanting the world to open up. If you liked Miss Peregrine's Home for Peculiar Children but wished it would stop lingering and start moving, this sequel is likely to be more satisfying. It offers travel, active threat, and a stronger sense that the series is heading somewhere larger than a single eerie premise.

It is also a good fit for readers who like young adult fantasy with gothic styling rather than high-fantasy sprawl. Riggs does not ask you to learn an enormous political system or memorize dense lore. He asks you to follow a distinctive mood, a vulnerable group, and a sequence of dangerous transitions. That makes the book accessible to reluctant fantasy readers as well as to younger readers ready for something darker than ordinary adventure fiction.

The less ideal audience is readers who came to the series mainly for the first book's singular novelty: the hidden house, the peculiar children as mysterious figures, the almost curated stillness of the setup. Hollow City inevitably loses some of that once the curtain is pulled back. It replaces mystery with motion. For many readers, that is the right exchange. For others, it will feel like a partial diminishment.

This is why the book is best recommended with precision rather than blanket enthusiasm. It is not the kind of sequel that converts everyone who was lukewarm on the opener, but it does reward readers who already like Riggs's blend of melancholy, monstrosity, and youth-centered loyalty. And for readers curious about where the trilogy heads next, Library of Souls makes more sense after Hollow City has done the messy but necessary work of expansion.

Context, comparisons, and final verdict

Within the Miss Peregrine sequence, Hollow City is the book that proves the series can survive outside its original frame. That is not a small achievement. Plenty of high-concept debuts create a memorable room and then have nowhere to go. Riggs does find somewhere to go: into a larger, sadder, more unstable world where the children must carry the meaning of the series with them rather than receive it from a single enchanted refuge.

That makes Hollow City a useful comparison point for readers thinking about sequel craft more generally. Like The Subtle Knife, it understands that a second installment should alter the emotional weather, not just add plot. Unlike Pullman, Riggs is less philosophically ambitious and more image-driven, but both writers know that middle books earn their keep by testing what the first volume merely introduced. And like A Monster Calls, though in a very different register, Hollow City uses young characters to carry fear, loss, and attachment with more seriousness than its marketing shorthand might suggest.

The final verdict is favorable, with reservations that are worth stating openly. Hollow City is not as self-contained or as freshly uncanny as the first Miss Peregrine novel. It can feel episodic, and some of its transitional business is more dutiful than transcendent. But it is also more urgent, more emotionally dependent on its ensemble, and more willing to expose its characters to a world shaped by ruin rather than shelter. The photographs still work. The gothic atmosphere survives movement. The found-family core gets stronger as danger increases.

So the short recommendation is this: read Hollow City if what you want from the series is a darker, faster, more outward-facing sequel that preserves its eerie visual identity while accepting some middle-book roughness. It is a solid professional recommendation for readers who like crossover fantasy with menace, melancholy, and group loyalty at its center. It may not be the most elegant book in the trilogy, but it is the book that turns the trilogy into one.
