The Hollow Places by T. Kingfisher is the kind of cosmic horror novel that sneaks up on you. It opens in a taxidermied-animal museum run by a woman's uncle, it moves fast, it makes you laugh, and then, without fanfare, it puts something through a hole in a wall that you won't stop thinking about. Kingfisher (the pen name of author Ursula Vernon) published the book in 2020, and it remains one of the most effective portal-horror novels written this decade.
What the book is about
Kara, recently separated and temporarily homeless, moves back into her Uncle Earl's museum of curiosities called the Glory to God Museum of Natural Wonders, Curiosities, and Taxidermy. While renovating a wall, she and her neighbour Simon, a barista who lives in the attached coffee shop, find a hole that shouldn't be there. Behind it: a corridor, and beyond that, a vast flooded world full of willow trees and silence and something that doesn't want company.
The other world is Kingfisher's greatest achievement in the book. It isn't a portal fantasy destination with rules and a map. It's wrong in the way a dream is wrong: internally consistent enough to be navigable, wrong enough to make your skin crawl. The willows stretch for what might be thousands of miles. There are bunkers. There are things written in languages neither Kara nor Simon can read. And there are the things in the water, which Kingfisher is smart enough not to over-explain.
The voice does a lot of work here
Kara narrates in first person and she's excellent company. She's self-deprecating without being helpless, funny without deflating the tension. Kingfisher uses Kara's voice to manage pacing in a way few horror novelists manage: the jokes arrive just before the dread peaks, which means the dread hits harder when it comes. It's a specific skill. Horror that makes you laugh and then scares you has a longer half-life than horror that just scares you.
Simon works similarly. He and Kara banter, they bicker over small things, and their friendship feels real enough that the stakes feel real. That's not a small achievement in a genre where secondary characters exist mostly to die. Neither Simon nor Kara is stupid, which is another relief. They make bad decisions, but they make them for reasons that hold up under scrutiny.
Kingfisher and the Lovecraft problem
Kingfisher is openly working in the Lovecraftian tradition here. The other world operates on cosmic-horror logic: humans are not the point, scale is incomprehensible, and knowledge doesn't help you survive it. If anything, it makes things worse. Readers who found The Fisherman by John Langan compelling will recognise the register immediately. Both novels use water, vastness, and willow-type imagery to generate dread from stillness rather than movement.
What Kingfisher does differently is refuse to take the cosmic horror posture seriously. Her narrator isn't a doomed academic or a haunted antiquarian. Kara is a divorced woman in her thirties who works in a weird museum and drinks too much coffee. She encounters the incomprehensible and her first reaction is frequently pragmatic rather than awestruck. This doesn't undercut the horror. It makes Kara more credible, which makes the horror land harder.
The Lovecraft influence also surfaces in the book's approach to knowledge as contamination, an idea Kingfisher handles with more nuance than its source. The things Kara and Simon bring back from the other world aren't monstrous artefacts. They're sensory impressions. That's the right instinct.
Where it earns its tension
The central set-piece, a multi-day expedition into the other world, is the novel's strongest section. Kingfisher builds it methodically: the geography shifts in ways that feel genuinely disorienting, the mood deteriorates in stages, and the moment the characters realise something is watching them is handled with real restraint. No jump. No sudden creature. Just an absence that changes shape.
The novel also earns its climax, which is harder than it sounds. Horror novels frequently dissolve in their final acts because the threat, once fully articulated, becomes smaller than the dread it generated. Kingfisher avoids this by keeping the antagonist partly obscured even at the point of maximum proximity. You understand enough to be terrified. You don't understand enough to feel safe.
Readers who enjoy The September House by Carissa Orlando will find a similar sensibility at work: a female protagonist in an impossible domestic situation, horror that takes her seriously, and a willingness to mix warmth with genuine dread. The tonal register is different, but the underlying respect for the reader is the same.
A few limitations worth naming
The pacing does compress in the second half in ways that occasionally feel rushed. The novel is short, around 300 pages, and some of the other-world sequences could have breathed longer. The romantic subplot is telegraphed early and resolved predictably. These are minor complaints against a book that largely does what it sets out to do, and does it with skill.
The Glory to God Museum is also underused. Kingfisher establishes it with affection and detail in the opening chapters, and then it becomes almost purely functional, a return point rather than a living setting. That's a shame, because the museum's energy, slightly absurd, slightly melancholy, deeply specific, is exactly the kind of grounding that makes horror fiction work.
The verdict
The Hollow Places by T. Kingfisher is a genuinely satisfying piece of cosmic horror that balances wit and dread more successfully than almost anything else in the genre published since 2020. Kingfisher's prose is clean and fast, her protagonist is credible, and the other world she builds stays troubling long after the book closes. If you've been looking for portal horror that takes the portal seriously, this is it.
