Burn of the Everflame Review: 6 Deaths, 4 Crowns, 1 Choice

Penn Cole finished a version of this book in 2024, pulled it two weeks before launch, and spent two more years rewriting it. What arrived on September 8 is the final volume of The Kindred’s Curse — a war story wearing a romance’s clothes. It asks one question: what would you pay to save a world built to exclude you? Here’s the full synopsis, every character dissected, and a verdict the five-star reviews won’t like.

Here are the numbers before the noise. A thousand-plus pages. A 35-hour audiobook read by seven narrators. 730 reader reviews inside ten days of release. The maths says finale; the page count says encyclopedia.

If you’ve followed Diem Bellator since Spark of the Everflame, you know the shape: a healer’s daughter who turned out to be heir to everything, and a boy who started as the villain. This is the book where both bills come due. Not gently.

Grab a cuppa. Spoilers stay vague until the summary says otherwise.

The 10-Second Verdict

The Book at a Glance

Detailed Summary — Full Spoilers From Here

You were warned. This is every plot beat, including who dies and how it ends.

Part 1: Four Crowns, One Captive

The book opens where Heat put Diem down: run through by a godstone blade, alive, and stranger for it. She wakes on Coeurlie in the Crowns’ keeping, the ruler of Fortos and heir to Ophiucae, carrying four Crowns’ worth of power — Lumnos, Fortos, Montios, Umbros. Her body now leaves godstone behind, a fact that terrifies everyone who learns it.

The Crowns are an alliance nobody wanted: ancient beings forced into the same room by a war none of them can win alone. They keep a secret from Diem for roughly the first quarter of the book, and the reveal of it resets her plans entirely.

Making Diem wait is a bold structural choice for a finale. It works about two-thirds of the time. The rest, you feel every page of it.

Part 2: The Mortal Question

Meanwhile, in the south, the real politics happen. Auralie Bellator — Diem’s mother, the rebellion’s spine — has built a mortal army around demands nobody in Emarion has ever conceded: mortal governors, equal rights for half-mortals, reparations, and her daughter back.

The rebels also discover Flameroot, a paste that blocks the Umbros magic Ophiucae uses to puppet people. It’s the only equaliser mortals have, and it turns the coming war from a slaughter into something resembling a fair fight.

This thread is the best writing in the book. Cole treats the mortal cause as genuinely just, not as set dressing for a love story, and the book is better for it.

Part 3: Luther’s Longest Year

Luther Corbois spends the book’s first act in Arbores with the rebel forces, training his illusion magic toward something like godhood — and believing Diem is dead. His father Remis carries a vision from Blessed Lumnos of Luther as a king, which Luther treats as prophecy he wants no part of.

His sister Alixe waits with the Lumnos Guard. Teller — Luther’s companion, and secretly Diem’s brother — refuses to believe she’s gone.

When word comes that Diem might live, the reunion the series has spent three books building finally lands. And then Cole makes you wait for the good part. More on that below.

Part 4: The Middle Four Hundred Pages

Here’s the part the one-star reviews are about. Reunited with everyone she loves, Diem responds by shutting all of them out — Luther hardest of all. She lies, withholds, and pushes, for hundreds of pages, while the people around her bleed for her war.

The mid-book reveal that lands hardest is Henri Albanon’s: he was there when Diem’s father Andrei died. Vance did the killing; Henri was forced to deliver the final blow. Henri chooses to help Diem anyway, knowing what the truth costs him.

The romance proper — the part romance readers came for — doesn’t arrive until around the 60% mark. When it comes, it’s earned and it’s lovely. The question you’ll keep asking is whether the wait needed to be that long, and I think the honest answer is no.

Part 5: The War of Flameroot

When the war finally starts, Cole writes it like she’s been saving up. Ophiucae’s army of mind-controlled slaves meets the rebels’ Flameroot and the Crowns’ powers, and the book’s pace doubles overnight.

The cost is real. Aemonn Corbois saves his brother Taran and is cut down by Jean Hanoverre. Alixe kills the god Xipherus with a ballista and dies doing it. And Teller — the book’s heart — stabs Ophiucae himself and is run through on the god’s sword.

Diem heals Teller’s body, but not in time. He dies in her arms with the family he only just found. If you don’t cry here, check your pulse.

Part 6: The Temple and the Price

Diem takes Sorrow’s Edge to the Temple and kills Ophiucae — her own birth father, once the tenth Kindred, a god who decided Emarion was broken past repair and had to be wiped clean. His death doesn’t finish the job. The heartstone demands a life for a life.

So Diem asks Luther to kill her. He does, at her command, with her consent, to complete the spell that saves the realms. It’s the series’ thesis in one scene: love as an act of terrible arithmetic.

Luther then tries to follow her into death. He survives it, refuses the bronze crown Mortal City offers him, and mourns for three months — until word comes that his mate might not be gone after all.

Part 7: The After

The afterlife chapters are the book’s strangest and best stretch. Diem meets the Kindred, the nine gods whose power she’s been carrying. They offer her the sort of bargains gods offer. She refuses them all — keeps her mating bond, and refuses to send Teller back in her place, even when he’s standing right there offering.

Teller stays by choice, with his father Andrei and their dead. He has a newborn son he’ll never meet in the flesh, and he chooses rest. It’s a devastating, humane piece of writing.

Part 8: King Luther

Diem returns during the Lumnos council, in front of everyone, and puts the crown back on Luther’s head herself. He becomes King of Emarion; she becomes the woman who died for the world and declined to stay dead.

They marry. Remis tells Luther he’s proud of him — the whole Corbois redemption in one line.

Part 9: One Year On

The epilogue is set a year later, and it’s a masterclass in payoff. Lily, a healer, has had Teller’s son — Andrei Teller Bellator, named for both his dead. Taran and Zalaric turn the restored palace into a school for war orphans, the Teller Institute for Talented Scholars. Eleanor and Auralie rebuild Mortal City together.

Family dinners at Diem and Luther’s house. A goat named Taran Junior. Everyone accounted for, living or dead. The saga ends with warmth instead of a sequel hook, and that’s rarer than it should be.

Characters — Every One Who Matters

Diem Bellator — the heroine problem

Let’s name the elephant: for the first half, Diem is genuinely hard to like. She withholds from everyone, lashes out at the people carrying her war, and refuses every hand extended to her. Early reviewers called her insufferable, and they’re not wrong.

The defence — and it’s a real one — is that Cole writes the trauma on purpose. Diem has been a weapon, a bargaining chip, and a god’s heir before her twenty-first birthday. Her cruelty is armour, and the book knows it’s armour.

What redeems her is the second half. She learns mercy precisely where her father chose annihilation, and she pays her own price rather than letting anyone else pay it for her. Whether the arc needed 600 pages to arrive is the 3.5-star conversation.

Luther Corbois — the best thing in the book

The boy who spent Spark as the antagonist completes one of the stronger redemption arcs in modern romantasy. He’s used and abused by nearly everyone in this book, including Diem, and he holds anyway — not as a doormat, but as someone who decided who he is and refuses to un-decide it.

The scene where he kills Diem at her own request is the series’ peak. A lesser book would frame it as tragedy. This one frames it as trust, and it guts you.

Ophiucae — the villain with a thesis

Diem’s birth father, once Omnus, brother to the Kindred. His position is that Emarion is broken past repair — so broken that mercy is just cruelty with better manners. The book takes him seriously, which is why the finale works.

You can argue with his maths. You can’t argue that he arrived at it cheaply.

Auralie Bellator — general first, mother second

The rebellion’s spine. Auralie spends three books being the mother who left, and this one being the leader who stayed. Her list of demands — governors, rights, reparations — reads like an actual political programme, which is more than most fantasy rebellions manage.

The reconciliation with Diem, and the armour she forges from Andrei’s ashes for her daughter, is the emotional spine the war hangs from.

Teller — the heart

Luther’s companion, Diem’s brother, the found family’s foundling. Teller gets the book’s best death and its best afterlife — a boy who spent his life searching for family, finding it, and then choosing to stay with the dead ones who waited for him.

The found family, briefly

Alixe dies like a Corbois, swinging. Aemonn dies saving his twin. Taran and Zalaric build a school. Henri confesses and pays. Eleanor rebuilds. No one is wasted; everyone’s ending rhymes with who they were.

Themes — What Cole Is Actually Saying

Three ideas carry the book. First: mercy is a decision you make when you have every right not to — Diem’s whole arc against her father’s. Second: inherited wars end only when someone accepts a cost they didn’t owe — the heartstone’s price in a sentence. Third: power doesn’t corrupt so much as it isolates, and the four Crowns nearly win by loneliness alone.

It’s not subtle, but finales shouldn’t be. The book wants to be felt, and it arranges its 400 deaths and dinners accordingly.

Compare With Other Works

How the finale stacks up against the other big romantasy war books:

Achievement — The Numbers

The commercial story is as loud as the plot:

That last row is the one I can’t get past. The book was done, and Cole chose to rebuild it rather than ship a finale she didn’t believe in. The rewrite shows — sometimes in the book’s favour, sometimes in its sprawl.

What Works

The war. Once the fighting starts, Cole writes mass battle like a veteran — clean geography, real costs, deaths that matter to the plot instead of to the body count. The Flameroot-as-weapon idea is genuinely clever world-building, and it lets mortals matter in a god fight.

Luther’s arc. From villain to king, with the series’ best scene handed to him at the Temple. His grief chapters — refusing the crown, trying to follow Diem, choosing to live — are the strongest stretch of writing in all four books.

The epilogue. Every thread paid off, every survivor accounted for, warmth instead of a sequel hook. In a genre addicted to cliffhangers, an actual ending feels like a gift.

Where It Hurts

The middle. Four hundred pages of Diem withholding, lying, and freezing out the people fighting for her. The trauma explanation holds, but the arc repeats the same beat — push away, regret, repeat — well past its welcome.

The length. Early readers said the book didn’t need to pass a thousand pages, and I agree. Cut 200 pages of the middle and this is a 4.5-star finale.

The romance timing. The mating bond the whole series is built on gets its payoff deep in the back half. That’s a long engagement for the emotional centrepiece.

The Verdict

★★★½☆ — 3.5 / 5.

Burn of the Everflame is a very good finale trapped inside a too-long book. The war, Luther’s arc, Teller’s death, and the epilogue are worth every hour the audiobook demands. The four hundred pages before them will test you, and the heroine will test you harder.

Read it anyway, if you’ve come this far. Endings this complete — endings that actually end — are worth the wait. Both waits.

FAQ

What order does the series go in?

Spark of the Everflame → Glow of the Everflame → Heat of the Everflame → Burn of the Everflame. The titles don’t alphabetise into order, so plenty of readers start wrong. Don’t be one of them — Spark plants every seed the finale cashes.

Do I need a recap of Heat first?

Yes. The godstone sword, the four Crowns, and Diem’s parentage are load-bearing. A 20-minute recap will save you 200 pages of confusion.

Does Diem survive?

Full spoilers: she dies at the Temple — Luther kills her, at her request, to complete the heartstone spell — and then returns from the After. She marries Luther in the epilogue, one year on.

Is this really the last book?

The saga ends here, and there’s no cliffhanger or back-door sequel hook. Cole’s site promises matching indie editions of the series in 2027, but story-wise, this is the end.
