Four books, all published, series complete as of September 2026. The Kindred’s Curse Saga is five stars and it’s the romantasy series I hand people first: real plot, real politics, a slow burn that earns every beat, and a world worth caring about. Books 1 through 3 are the peak. Burn of the Everflame closes it out and is the weakest of the four, almost entirely because of the ending. Start with Spark of the Everflame anyway.
The series at a glance: four books, complete. Romantasy and epic fantasy romance. Single POV throughout. Spice sits at a 2. Roughly 2,700 pages across the four Kindle editions. I read all of them on Kindle and finished the last one in September 2026.
I have a complicated relationship with romantasy. I love the genre in theory and have been burned enough times by thin world-building and romance that does all the heavy lifting while the plot sits in the corner doing nothing. So when I picked up Spark of the Everflame, I was ready to be mildly entertained and moderately disappointed. Instead I tore through the first three books and then spent three years in the same waiting room as every other fan, staring at Penn Cole’s Instagram for a Book 4 release date that did not exist.
That wait is over. Burn of the Everflame came out on 8 September 2026, it is 880 pages, and I read it on Kindle in a few days because of course I did. So this is no longer a review of an unfinished series. It’s a review of a complete one, and that changes what I have to say about it.
The world Penn Cole builds is called Emarion, a mortal realm colonized by the gods and ruled by their offspring, the Descended, demigods with magic, status, and a long history of keeping mortals firmly beneath them. Our protagonist is Diem Bellator, a mortal healer from a poor village who gets thrust into the world of Descended royalty after her mother vanishes under circumstances that are very much not simple. The setup sounds familiar because the bones of it are familiar, but what Cole does inside that structure is sharper and more plot-dense than most of the genre manages.
The series follows a single POV through Diem’s eyes, which is the right call. Cole’s pacing depends on information being revealed at exactly the right moment, and a wider POV structure would have undercut that. If you need your love interest fully declared by chapter ten, adjust your expectations significantly. The tension here is the kind that makes you read another three chapters at 11pm when you had absolutely planned to stop. On spice: there’s some, it’s on the page when it shows up, and it never takes over the story. If you want spice front and center instead, my Poison Daughter review covers a standalone at the top of the scale.
Trigger warnings before you dive in: on-page violence, on-page intimate content, themes of oppression and systemic injustice, and some dark content around child death and domestic violence in the earlier books. Nothing gratuitous, but worth knowing. This is not a cozy read. It is, however, an addictive one. If you’re new to romantasy this is a strong entry point. If you’re a veteran of the genre who’s tired of plot taking a back seat to romance, this is specifically for you.
Vibe Check: Is This an Easy Read?
The writing is propulsive, and Cole’s style swings between tense political intrigue, genuine laugh-out-loud banter, and emotional gut-punches with impressive fluidity.
Pacing-wise, Book 1 takes a chapter or two to find its footing, then locks in and doesn’t let go. The emotional intensity builds across the series in a way that makes each book feel higher-stakes than the last without losing the humor and banter that makes the characters worth caring about in the first place. If you’ve read From Blood and Ash by Jennifer L. Armentrout or A Court of Thorns and Roses by Sarah J. Maas, you’ll feel the same DNA here. Cole is playing in that space and, in my opinion, doing some things better. For another romantasy, I reviewed Hollow by Caroline Peckham with no spoilers.
Book 1: Spark of the Everflame
A setup book that never feels like one, and it ends somewhere that makes Book 2 non-optional.
Book 1 is doing a lot of work: building the world, establishing the class dynamics between mortals and Descended, and introducing a cast of characters that grows substantially as the series goes on. It does all of it without ever feeling like it’s forcing information into you. The mystery around Diem’s mother is what drives the plot forward, and Cole parcels out answers at a pace that kept me suspicious of everyone for the entire book.
The love interest is introduced early and is immediately compelling for reasons I won’t get into. The slow burn starts here and it is genuinely slow, which I mean as a compliment. The tension is built carefully enough that when anything does happen, it hits harder than it would have with a faster burn.
Book 2: Glow of the Everflame
Where the romantasy turns out to be a political story about power and complicity underneath.
Diem gets pushed harder here. The line between good and evil turns out to be a lot blurrier than anyone in Emarion wants to admit, and the stakes for the romance and the wider world escalate at the same time. Cole manages both without shortchanging either.
There are reveals in Book 2 that reframe things you thought you understood from Book 1 in ways that made me want to go back and reread the early chapters immediately. Cole is apparently hiding things in plain sight from page one of the series, and Book 2 is where you start to see the edges of how deliberate the construction actually is. The foreshadowing is doing serious work and you won’t catch all of it the first time through.
Book 3: Heat of the Everflame
The longest and darkest of the first three: war arrives, allegiances fracture, and nobody gets an easy out.
This is the book where the emotional weight of everything built across the first two comes due, and the bill is steep. If you thought you had a handle on where this story was going, Book 3 will disabuse you of that notion.
Some readers have found Book 3 slower given its length, and that’s not an entirely unfair criticism. It’s a bridge book doing the heavy work of setting up an enormous finale, and it carries that weight visibly in places. But the character moments are some of the best in the series and the ending left me genuinely furious in the way that only a book you’re completely invested in can. For three years, that was where the series stopped.
Then it didn’t.
Book 4: Burn of the Everflame
The best war writing in the series, a middle that drags, and an ending that doesn’t quite land. Still worth reading.
Let me start with the part that isn’t complicated. The action sequences actually land, and there are stretches in here as sharp as anything Cole has written. If you’ve read the first three, you’re going to read this one, and you should.
Now the complicated part. Diem and Luther spend an enormous stretch of this book not talking to each other, and a lot of the plot is stacked on top of that silence. Other readers have been loud about it and they’re right. It drags the middle. There’s a shorter, better version of this book, and it’s the one where two people who have survived what these two have survived have a single honest conversation in the first half.
The ending is where it lost me, and I’m staying vague because this post has been spoiler-free for four books and I’m not breaking that now. Three things. It leaves threads hanging that the first three books spent real effort setting up. What it does resolve, it resolves too cleanly for a story that spent three books insisting nothing here comes free. And one character’s landing spot I flat out did not buy, not because it was sad or unfair, but because it wasn’t the person the series had been building.
None of that makes it a bad book. It makes it the weakest of the four, which is a different sentence entirely.
Final Thoughts
If you’re a romantasy reader who wants plot, character and actual stakes alongside the romance, The Kindred’s Curse Saga is exactly what you’re looking for. Diem is genuinely interesting to spend four very long books with, and Emarion is a world I’d go back to.
Four books of landing every beat would be rarer than this genre usually manages, and the first three are good enough that I’d hand them to someone tomorrow knowing full well how it ends.
So start with Spark of the Everflame, read all four, and then come argue with me about that ending. I’d like to know if I’m the only one.
