Verdict: A 586-page epic sapphic romantasy built on a genuinely glacial burn and an unusually well-managed world — immersive, tense and carried by a heroine who actually grows, undercut by a pace that loses readers outright and a cliffhanger with no sequel date attached.
Best for: Readers who want a long, slow, atmospheric fantasy where the tension is in restraint rather than heat, who like a captive-and-captor dynamic played as protection, and who are not in a hurry.
Heat level: ★☆☆☆☆ (1/5 — romance.io’s lowest band, “glimpses and kisses”; the book calls itself a glacial burn and means it)
Rating: ★★★★☆ (4.0/5 — a 4.33 Goodreads average from a heavily ARC-weighted readership, on a book that ends unresolved)
Tropes: Enemies-to-lovers, glacial burn, captive and captor, fish out of water, arranged-marriage escape, chosen vessel, exiled love interest, only soft for her, curse breaking, trilogy opener.
Cages of Alyssum is Ava Hardwick’s self-published opener to The Moonbond Trials — a 586-page sapphic romantasy in which Alyssum, a Treaty Princess of Lunamor, is violently attacked by the man she is contracted to marry, and escapes the only way available to her: across the Threshold, into a fog that is supposed to strip the memories of anyone who returns, and into a village run by an exile called Vayen Videa who takes one look at her and refuses to let her leave.
It holds a 4.33 average across 217 Goodreads ratings and 4.6 across 136 on Amazon, with 86% at four stars or above and effectively no negative ratings. Two caveats belong next to that number: the book is only three months old, and 83 of those 217 ratings carry written reviews, a great many of which identify themselves as ARC copies. Both halves of that split are worth understanding before you start.
What Is Cages of Alyssum About?
This is epic romantasy rather than the compact kind, and the page count is a statement of intent. Where a 300-page romantasy compresses its world into whatever the couple needs, Hardwick builds two societies — the treaty-bound court of Lunamor and whatever exists beyond the Threshold — and lets the reader learn the second one at the same speed the heroine does. Multiple reviewers name that structure specifically as the reason the world-building never overwhelms them: Alyssum knows nothing, so nothing is assumed.
Alyssum is introduced through confinement rather than ignorance, though she has both. She is a princess whose value is contractual, whose betrothal is a treaty clause, and whose escape route runs through a place everyone has told her is uninhabitable. Vayen is the inversion: lowborn, exiled, in command of the only shelter available, and convinced that Alyssum is a Goddess Vessel who can break the curse on her people. The romance runs on that asymmetry — one woman needs somewhere to be, the other needs her to be a specific thing — and it takes most of 586 pages to resolve into anything.
What Makes This Sapphic Romantasy Work
- Alyssum’s arc: The most-praised element. Readers describe her moving from naive and helpless to brave and willing, and even the three-star reviews lead with how much they liked watching it happen.
- The world-building method: The reader learns Morwyn through a protagonist who knows nothing, and reviewers repeatedly say this is why a long fantasy never felt like homework.
- The tension: “Every moment feels earned” is a direct quote about the glacial burn, and the reluctant-protector beats — the lingering looks, the catch after a stumble — are what readers quote back.
- The tonal mix: One reviewer called it dark fantasy and cosy fantasy in the same book, which is an odd combination and an accurate description of a story about violence that spends most of its time in a village.
- The supporting cast: Readers single out the people Alyssum meets on the way as characters they wanted to learn about rather than furniture, which is unusual praise for a book this focused on two women.
Book Synopsis
Alyssum has been a Treaty Princess of Lunamor her whole life, which means her marriage was decided before she had opinions and her worth is measured in what it keeps from happening. She has been told since childhood that the Threshold is not to be crossed — the fog takes the memories of anyone who comes back, and beyond it there is nothing but bog and demons. It is a very effective story for keeping a princess where she is supposed to be.
Then her betrothed attacks her, and the treaty that made the marriage inevitable becomes the thing she has to escape rather than the thing she has to honour. She crosses the Threshold because it is the only direction nobody will follow her in, and what she finds on the other side is not a bog. It is a village, functioning, inhabited and organised, run by a dark-haired exile who watches her arrive with an interest that is not hospitality.
Vayen Videa is lowborn, stoic and entirely uninterested in Alyssum’s rank. What she is interested in is the possibility that this princess is a Goddess Vessel — the one person capable of breaking the curse laid on Vayen’s people — and she is not prepared to let that possibility walk back into the fog. Alyssum has rope marks on her wrists and every reason to hate her, and the problem is that hating her turns out to be difficult in the specific way that becomes a different problem entirely. The question underneath the whole book is whether a woman who has only ever been valuable for what she is can survive being wanted for what she can do.
My Review
The character work is the reason this book earns its reception. Alyssum starts the novel as a person things happen to — a treaty clause with a pulse — and the arc Hardwick gives her is genuinely gradual: she does not become competent in a chapter, she becomes slightly braver repeatedly, over hundreds of pages, in a way that makes the ending mean something. Even the reviewers who found the book too slow lead their criticism by saying how much they liked that arc, which is the clearest possible signal it is working.
The second strength is a technical one and worth naming because so few epic fantasies manage it. Hardwick uses Alyssum’s total ignorance of the world beyond the Threshold as the delivery system for the world-building, so the reader is never being lectured — she is being told things at the same moment the heroine needs them. Reader after reader says some version of “with most fantasy it takes a while to learn the world, and I had no trouble with this one.” At 586 pages that is not a small achievement.
Where it struggles is exactly what the subtitle promises, and this is the dominant complaint. The book calls itself a glacial burn and it is not exaggerating; one reader abandoned it at 65% calling it extremely boring and slow, and a three-star reviewer who loved Alyssum and loved the supporting cast said her only issue was that she struggled to push through more of it than she wanted to. Her recommendation is the honest one: this is a relaxed read without much action. Eleven per cent of ratings sit at three stars and they are all describing the same experience.
The other thing to weigh is structural rather than stylistic. The ending is a hard cliffhanger — one reviewer calls it the meanest cliffhanger and forgives it, another says she cannot wait for the next book — and as of August 2026 there is no second Moonbond Trials volume listed anywhere. The book is three months old, so that is not a criticism of the author’s pace; it is simply information you need. You are starting a trilogy at the point where only the first third exists.
One expectation to reset firmly: romance.io bands the heat at 1 out of 5, glimpses and kisses. The tension is constant and readers describe it as electric, but it is tension, not content. If explicit heat is what you want from romantasy, this book will frustrate you for 586 pages and then stop.
My honest note: The best-constructed heroine’s arc of any book in this batch, inside a novel that asks for real patience and does not pay it all back yet. Start it if slow is a feature; wait if it is not.

How Spicy Is Cages of Alyssum?
romance.io bands it at 1 out of 5 and labels it “glimpses and kisses,” the lowest rung available to a book with a romance in it. The marketing agrees for once: the Amazon subtitle reads “A Slowburn Sapphic Romantasy” and the publisher’s own copy calls the romance a glacial burn. Readers do not experience that as a shortfall — the recurring description is of constant tension in which the smallest interactions feel important, and one reviewer summarises it as every moment feeling earned. This is a descriptive number, not a criticism.
The thing that genuinely needs flagging is content rather than heat. The novel opens with Alyssum being violently attacked by her betrothed, and at least one reviewer leads her entire review with a sexual assault content warning. Captivity and physical restraint are also on the page — the rope marks are in the publisher’s own blurb. For the same band, Cinders of Yesterday sits at 1/5 with a comparably deferred romance, and A Crown of Deceit & Ruin at 2/5 for readers who want a fraction more.
Who Should Read This Book?
You’ll likely love it if: you want a long fantasy where the world is properly built, you like a heroine who earns her competence slowly, restraint reads as tension to you rather than absence, and 586 pages is an evening well spent.
You may want to skip it if: you need action, you want on-page heat, you resent cliffhangers with no publication date behind them, or a book that takes its time feels like a book that is stalling.
In short: a properly built epic romantasy with an exceptional heroine’s arc, sold accurately as a glacial burn and best started by readers who mean it.
What Readers Are Actually Saying (August 2026)
This book is three months old, which shapes everything about its discourse. There are 217 Goodreads ratings and 83 written reviews — a ratio that is far too high to be organic and is explained by the number of reviews that open by identifying themselves as advance copies from the author. That does not make the enthusiasm false, but it does mean the 4.33 average is measured on a self-selected readership, and the Amazon figure of 4.6 across 136 ratings is not more neutral so much as differently skewed. There is no audiobook — Libro.fm does not stock it — no trade coverage and no Reddit footprint yet.
Why readers love it (according to the discourse): Alyssum first. Her growth from naive and somewhat helpless to brave and willing to face the unknown is described in almost identical language by reviewers who otherwise disagree about the book. The world-building method is second and gets named with unusual precision — readers say the book eases them into Morwyn rather than plunging them in, and credit the heroine’s ignorance for it. Third is the tension: the reluctant protector, the watching green eyes, the hand always ready to catch her, all quoted back approvingly. Fourth, and the most interesting piece of praise, is the tonal register — one reviewer describes it as simultaneously dark fantasy and cosy fantasy, which for a book that opens on an assault and spends most of its length in a village is a fair reading. The minority view worth flagging is from readers who normally dislike slow romance and say the earned quality of it converted them.
What readers argue about and complain about: Pace, and only pace, but seriously. The mechanism is that 586 pages of glacial burn leaves long stretches with no action to carry them — one reader put the book down at 65% and called it extremely boring and slow, and a three-star reviewer who praised the heroine, the growth arc and the entire supporting cast said her one issue was that she struggled to push through more parts than she wanted to. Her closing advice doubles as the fairest description the book has: if you want a relaxed read without too much action, this is it. Second: the cliffhanger, which readers describe as mean and forgive because they liked the book, but which lands differently when there is no announced sequel. Third, minor and structural: the heat band will disappoint readers who came in on the word romantasy without reading the subtitle. The genuine split is between readers for whom slow is atmosphere and readers for whom slow is stalled.
The series question everyone should ask first: This is the one to pay attention to. Cages of Alyssum is billed as the first book in a trilogy, it ends on a cliffhanger that reviewers call the meanest they have read this year, and as of August 2026 no second volume is listed on Amazon or Goodreads. The book was published in May 2026, so there is nothing alarming about that — but if you are the kind of reader who needs to know when the next one lands, the answer right now is that nobody does. Borrow it, enjoy it, and be honest with yourself about how well you handle waiting.

If You Loved Cages of Alyssum, Read These Next
A Crown of Deceit & Ruin is the closest match on this site — a slow-burn romantasy with a captive heroine, a deception plot and its own cliffhanger — while Cinders of Yesterday shares the 1/5 band with a completed plot, and The Curse of the Goddess runs the same curse-breaking engine far hotter and resolves.

The Bottom Line
Cages of Alyssum sets out to be an epic sapphic romantasy that earns every step of its romance, and it delivers three things properly: a heroine whose growth is the actual subject of the book, a world taught rather than dumped, and a tension so sustained that readers quote individual gestures back. What it does not deliver is momentum, heat, or an ending — and with no sequel announced, that last one has an open-ended cost attached. If patience is something you have, this is one of the better-built romantasies of 2026. Check Cages of Alyssum on Amazon →
