Pestilence Review — Is It Worth Reading?

This post contains affiliate links. As an Amazon Associate we earn from qualifying purchases, at no extra cost to you.

Verdict: A captivity road-romance with one of the strongest slow-burn signals in Kindle Unlimited and the widest low-star tail on our shelf — and the objection that dominates its criticism is not the one you have been told about.

Best for: Readers who choose dark captivity romance deliberately, who want an immortal hero with a genuine arc, and who can hold a book at arm’s length while its moral logic falls apart.

Heat level: ★★★★☆ (4/5 — “explicit open door” on romance.io, from 649 reader ratings)

Rating: ★★★★☆ (3.7/5 — a 3.86 Goodreads average with 10% of its 134,311 ratings at one and two stars, the widest split on our slow-burn shelf)

Tropes: Slow burn, enemies to lovers, captivity, dystopian apocalypse, immortal hero, virgin hero, vengeance, forced proximity, dark romance, single POV.

This is an LRR evidence review. We have not read this book cover to cover; every claim below is built from named public sources — Goodreads, StoryGraph, romance.io, Amazon, Smart Bitches Trashy Books, Subjectify and the Trigger Warning Database — and where the evidence stops, we say so rather than filling the gap.

Pestilence is Laura Thalassa’s 2018 self-published romantasy, re-released by Bloom Books in August 2023 and now a USA Today bestseller: the Four Horsemen have arrived, the world is ending, Sara Burns is chosen by lot to assassinate one of them, and when her arrow and her fire fail to kill him he takes her with him.

It carries a 3.86 average across 134,311 Goodreads ratings, 3.68 on StoryGraph from 7,010 reviews, 3.77 on romance.io from 649, and 4.3 from 34,087 Amazon ratings. The number that matters is not the average — it is the distribution. Roughly 10% of ratings sit at one and two stars, against about 1% for the sports romances on the same shelf. This is a genuinely divisive book and the average hides it completely.

What Is Pestilence About?

This is post-apocalyptic dark romance, and both halves of that are load-bearing. The apocalypse is real: the Horsemen have ended technology, and Pestilence rides ahead of a plague that kills everyone in its path. The darkness is structural rather than atmospheric — Sara is his prisoner for most of the novel, dragged along a road she cannot leave, and readers do not dispute that. What they dispute is what the book thinks about it.

Sara is introduced through an act — she shoots him, sets him alight, and fails — and Pestilence through what he does next, which is retribution. The book is single first-person POV, Sara only: romance.io carries a first-person tag with 29 votes and no dual-POV tag at all. That matters, because the hero’s interiority is exactly what the book’s critics say is missing from its resolution.

What Makes This Dark Captivity Slow Burn Work

• The signal is genuinely strong: 42 of 649 romance.io raters tagged it slow burn with zero insta-love tags, alongside 60 for enemies to lovers. For a captivity romance, that combination is unusual and it is earned — the relationship starts with an attempted murder.
• The hero has an arc rather than a redemption montage: around seven of the thirty most-visible Goodreads reviewers name his development specifically, and it is the most consistent positive in the reviews.
• It is compulsively readable: about eight reviewers use words like addictive or unputdownable. Whatever else is true, the book moves.
• The heroine has a voice: roughly six reviewers name Sara’s sarcasm and wit as what makes the captivity bearable to read.
• It commits to being dark: about five reviewers name the moral complexity as a feature. This is not a dark-adjacent book with a soft centre, and the reviews that praise it and the reviews that condemn it agree on that much.

Book Synopsis

Five years ago the Four Horsemen appeared and the modern world stopped. Electricity is gone, aircraft are gone, and the survivors have organised themselves around the certainty that the riders cannot be killed. Now Pestilence is heading for Sara Burns’s corner of British Columbia, and the town draws lots for who will try anyway.

Sara draws the short one. She shoots him with an arrow, sets him on fire, and watches him burn. He does not die. He heals, he remembers, and he decides that the woman who did it will accompany him on the rest of his ride — through every town he empties, for as long as it takes.

What follows is a road novel with a captor and a captive: a horse, a series of abandoned houses, and two beings with nothing in common except the road and the fact that neither can leave it. He is not human and does not pretend to be. She is running out of ways to fight him and refusing to stop. The question the book runs on is whether anything between them can be real when one of them holds every card — and whether the plague riding behind them is something he chooses or something he is.

My Review

The premise is the best thing here and it is genuinely audacious: a romance that opens with an attempted assassination and continues as a captivity, with an immortal who is the literal agent of mass death. About eight of the thirty most-visible Goodreads reviewers call it addictive; whatever else is true, Thalassa can make you turn pages.

The burn is also real, which is why the book is on our shelf at all. Forty-two of 649 romance.io raters tagged it slow burn and not one tagged insta-love, and the structure supports that: the relationship has to travel a very long way from an arrow in the back. The hero’s arc is the most-praised element, at around seven reviewers, and Sara’s sarcasm is what makes the middle stretches readable, at about six.

Now the part most reviews of this book get wrong. The consent conversation is the one everyone expects, and it is not where the criticism actually concentrates. The dominant objection is about the hero’s agency. Smart Bitches Trashy Books graded this book a D, and Elyse’s central point is structural rather than squeamish: Pestilence could have stopped the plague at any moment and simply chooses to at the end, which makes every death behind him retroactively optional and costs him nothing at the resolution. About eight of thirty Goodreads reviewers arrive at the same complaint independently, describing the moral messaging as disturbing or inconsistent, and about six specifically object to the heroine becoming complicit in mass death.

The captivity criticism is real too, and it is worth reporting precisely. About seven reviewers object to romanticised captivity and about five name Stockholm-syndrome dynamics; four raise arousal-during-injury scenes as a consent problem. Here is the thing that makes this book unusual: readers do not dispute the facts, only the framing. Nobody argues about whether Sara is a prisoner. The critics object to the book celebrating it. And the reader base itself declines to tag the consent framing at all — abduction appears 48 times and cruel hero 27 on romance.io, while no dubious-consent tag appears anywhere in the book’s 43-tag list. Dub-con is a label the critical minority applies from outside; it is not how this book’s own readers file it. Both facts are true and we are not adjudicating between them.

The last real complaint is structural: about seven reviewers name thin worldbuilding, and several independently describe the same repetitive loop — travel, find a house, rest, repeat. About four call the ending abrupt.

My honest note: A properly dark, properly slow captivity romance with a resolution that lets its hero off. If you want the darkness and can tolerate the moral shortcut, it earns its place. If you need the book to know what it thinks about what it is doing, read the Smart Bitches review first.

Burn speed	VERY SLOW — Slow-Burn Signal 6.5 (42 slow-burn tags / 649 romance.io ratings, zero insta-love)
Enemy intensity	L5 mortal enemies, asymmetric at the start — she attempts to kill him on page one and he is the agent of her species’ extinction. Tagged enemies to lovers 60 times, the highest count on the book
Consent and power	Contested, and the facts are not. Sara is held captive; abduction is tagged 48 times and cruel hero 27. No dubious-consent tag appears in the book’s 43-tag list. About seven reviewers object to romanticised captivity and four raise arousal-during-injury as a consent problem; the reader base files it as abduction rather than dub-con. We report both and adopt neither
POV	Single, first person, Sara only — no dual-POV tag exists on romance.io

Content notes	Reader-sourced and extensive. StoryGraph graphic tier: animal cruelty, child death, torture, genocide, war, murder, gun violence, physical abuse, kidnapping, body horror, fire injury, medical trauma, terminal illness, death of a parent, grief, blood, sexual content.

Goodreads reviewers name child death as the most common stopping point, and several flag intimate scenes occurring while people die nearby

Is Pestilence on Kindle Unlimited?

Yes. Pestilence is included with Kindle Unlimited as of 22 August 2026, verified on its own Amazon product page by reading the Kindle format swatch rather than trusting a search tile. Check the current status on Amazon before you download — this title has a Bloom Books trade edition behind it, and trade involvement is one of the more common reasons a book leaves the programme.

Audio inclusion is unverified and there is a second complication here. Two entirely different audio products exist for this book, one of them abridged, and neither has been confirmed as included with a Kindle Unlimited subscription. The details are in the discourse section, because getting the wrong one is a real risk.

How Dark and Spicy Is Pestilence?

Band 4 of 5 on romance.io, labelled “explicit open door,” from 649 reader ratings, and about four of the thirty most-visible Goodreads reviewers name the spice as a draw. On the heat axis it is straightforward.

The darkness axis is where this book needs care, and it needs more of it than almost anything else on our shelf. StoryGraph readers place animal cruelty, child death, torture, genocide and war in the graphic tier, and Goodreads reviewers name child death as the single most common reason people stop reading — one describes quitting over children being harmed after the heroine begs him not to. Several reviewers independently flag intimate scenes taking place while people die nearby. That is the flavour of the book: not gothic dread but sustained, literal mass death with a romance running through it. Consent is contested rather than settled — see the element table above, where we set out what readers do and do not tag. For a dark slow burn with a narrower and better-signposted darkness, The Sweetest Oblivion sits at the same heat band inside a mafia arranged marriage.

Who Should Read This Book?

You’ll likely love it if: you choose captivity romance deliberately rather than stumbling into it, you want an immortal hero with an actual arc, you like a heroine who stays sarcastic under pressure, and you read dark romance for the discomfort.

You may want to skip it if: child death or animal cruelty on the page is a hard limit, you need a book to have a coherent moral position on its own events, romanticised captivity is a dealbreaker, or thin worldbuilding will pull you out of an apocalypse.

In short: the darkest genuine slow burn in Kindle Unlimited, with a resolution that lets its hero off the hook.

What Readers Are Actually Saying (August 2026)

The discourse on this book has settled rather than raged. There is no active 2026 argument about its consent politics that we could find — the debate is preserved in the review record rather than being relitigated, and the absence is itself worth reporting. What is live is audio: GraphicAudio has been rolling out dramatised adaptations across the series, which is bringing a 2018 backlist title to a new audience. The earlier resurgence was the Bloom Books re-release in August 2023, which put it on the USA Today bestseller list. There is no Publishers Weekly, Kirkus, Library Journal or Booklist review. Reddit: unknown / not accessible — reddit.com is blocked from our research environment and nothing has been substituted for it.

Why readers love it (according to the discourse): readability first — about eight of thirty call it addictive or unputdownable. Then the hero’s arc at about seven, the heroine’s voice at about six, and the enemies-to-lovers execution at about six. Moral complexity is named as a positive by about five, and the premise and the prose by about four each. Subjectify’s Karen Rought represents the sympathetic reading, describing scenes of the hero gently tending Sara’s wounds — the same material the book’s critics cite.

What readers argue about and complain about: Moral messaging, above everything — about eight of thirty describe it as disturbing or internally inconsistent, and this is where the professional and reader criticism converge. Smart Bitches Trashy Books graded it a D on precisely this point: the hero could have stopped the plague at any time, so the ending costs him nothing. Second, worldbuilding and plot, at about seven, with several naming the same repetitive travel-rest-repeat loop. Third, romanticised captivity, at about seven, with five more naming Stockholm-syndrome dynamics and four raising arousal-during-injury as a consent question. About six object to the heroine becoming complicit in mass death, four call the ending abrupt, and two name slut-shaming. The shape of the split is unusual and worth understanding: praise clusters entirely around readability and criticism clusters entirely around ethics. Nobody argues the book is boring and immoral — readers agree it works and divide on whether the moral problem disqualifies it.

On audio, be careful, because two different products share this title. The unabridged audiobook is narrated by Susannah Jones, runs 11 hours 23 minutes, and was published by Lavabrook in May 2018. A separate GraphicAudio dramatised adaptation from 2025 uses a cast of more than twenty-eight actors with sound effects and music, and runs 9 hours 37 minutes. Audible describes the adaptation as unabridged; Libro.fm and Barnes & Noble classify it as abridged, and the runtime settles the argument — nearly two hours shorter than the full recording is an adaptation, not the book. Libro.fm stocks only the adaptation. We could not load the Libro.fm page itself, which is why there is no Libro.fm link on this review: we do not link an edition we could not verify, and we would not link an abridgement as though it were the novel.

The series question everyone should ask first: The Four Horsemen is complete at four books, each with a different couple, and the ratings climb steadily — Pestilence 3.86, War 4.02, Famine 4.18, Death 4.28. Book one is the weakest-rated entry in its own series, which is unusual and directly relevant if you are deciding whether to start. This volume resolves its couple arc with an epilogue set five years later; the epilogue opens the next conflict, so treat it as a resolved romance inside an unresolved world rather than a cliffhanger — only two romance.io readers tagged it as one.

Frequently Asked Questions

Is Pestilence on Kindle Unlimited?

Yes, included with Kindle Unlimited as of 22 August 2026, verified on its own Amazon product page rather than a search tile. It has a Bloom Books trade edition behind it, and trade involvement is a common reason titles leave the programme, so check before you download.

Is Pestilence a slow burn?

Yes, and a strong one. 42 of 649 romance.io raters tagged it slow burn with zero insta-love tags. The relationship starts with an attempted assassination and a captivity, which is a very long way to travel.

Is Pestilence dub-con?

Contested, and we are not adjudicating it. The captivity is not disputed by anyone — abduction is tagged 48 times. But no dubious-consent tag appears anywhere in the book’s 43-tag romance.io list, while about seven of thirty reviewers object to romanticised captivity and four raise arousal-during-injury scenes. Readers tag the mechanism and decline to tag the framing.

What is the biggest criticism of Pestilence?

Not the consent question, which surprises people. It is the hero’s agency: he could have stopped the plague at any point and simply chooses to at the end, so the resolution costs him nothing. Smart Bitches graded the book a D on this point and about eight of thirty Goodreads reviewers reach it independently.

Is there a cliffhanger?

Not really. The couple arc resolves with an epilogue set five years later, and only two romance.io readers tagged the book as a cliffhanger. The epilogue does open the next conflict, so it is best described as a resolved romance inside an unresolved world.

Do I need to read the whole Four Horsemen series?

No. The series is complete at four books and each follows a different couple with a different horseman. Worth knowing before you start: Pestilence is the weakest-rated entry in its own series, with War at 4.02, Famine at 4.18 and Death at 4.28.

Which Pestilence audiobook is the real one?

The unabridged recording is narrated by Susannah Jones and runs 11 hours 23 minutes. A 2025 GraphicAudio dramatised adaptation with a cast of twenty-eight runs 9 hours 37 minutes — nearly two hours shorter, so it is an adaptation regardless of how it is labelled. Libro.fm stocks only the adaptation.

Does the author publish content warnings?

No public warning set was found, with a caveat: laurathalassa.com was serving a site-wide maintenance placeholder when we checked, so a warnings page could exist and be temporarily unreadable. Everything in our content notes is reader-sourced, and StoryGraph’s graphic tier for this book is unusually long.

If You Loved Pestilence, Read These Next

If the immortal-hero-and-mortal-woman structure was the draw, The Serpent and the Wings of Night by Carissa Broadbent puts a human in a vampire tournament and carries zero insta-love tags across the largest rating base on our shelf. If it was the dark power imbalance rather than the fantasy, The Sweetest Oblivion runs a mafia arranged marriage at the same heat band. And if you want the same non-human premise with a completely different tone, Morning Glory Milking Farm is the shortest and warmest book on the shelf. All three sit on our best slow-burn romance on Kindle Unlimited guide, and the wider shelf is in Book Reviews.

The Bottom Line

This is the most ambitious premise on our slow-burn shelf: an apocalypse, an immortal agent of mass death, and a romance that has to start from an attempted murder and travel the entire length of a book. It mostly works — the burn is genuine and measurable, the hero’s arc is the most-praised element, and eight of thirty reviewers could not put it down. Against that, the worldbuilding is thin, the middle repeats itself, and the ending lets the hero off a hook he was holding the whole time, which is the objection that unites its harshest professional review with a quarter of its readers. Ten percent of its ratings sit at one and two stars, and those readers are not confused. Check Pestilence on Amazon →

On the Eikna scale, Pestilence ranks as a high-concept dark captivity slow burn — the strongest premise on our Kindle Unlimited shelf, held back by thin worldbuilding and a resolution that costs its hero nothing, and best approached for the darkness and the arc rather than for coherence.
