Everyone thought the hardest part of Basgiath War College was surviving the Threshing. They were wrong. Rebecca Yarros didn't just up the ante with Iron Flame; she basically set the table on fire and asked us to keep eating. It’s a massive, chunky book that feels like two novels shoved into one binding, and honestly, that’s exactly why the fandom is still arguing about it months after the initial hype died down.
If Fourth Wing was the honeymoon phase—all adrenaline, new dragons, and "oh my god he's going to kill her/kiss her"—then Iron Flame is the grueling reality of what happens when the revolution actually starts. It’s longer. It’s darker. And yeah, it’s a lot more complicated than just flying around on Tairn and looking cool.

Violet Sorrengail isn't the fragile girl from the first book anymore. But she isn't a superhero either. She’s a nineteen-year-old with Ehlers-Danlos Syndrome (though the book calls it chronic joint hypermobility) who is trying to figure out how to keep her secrets from her dragons, her boyfriend, and a military hierarchy that wants her dead. It's a lot.
The Basgiath Pressure Cooker
The first half of the book is claustrophobic. You've got Violet back at school, but everything is different. Her brother Brennan is alive, which is a massive shock to the system. Her mom, General Sorrengail, is still being... well, General Sorrengail. But the real tension comes from the new Vice Commandant, Varrish.
Varrish is the kind of villain you just love to hate. He isn't some distant threat; he’s right there in the hallway, watching Violet’s every move, trying to find a weakness in her bond with Tairn and Andarna. The psychological warfare in these chapters is intense. Yarros spends a lot of time on the "Rider's Quadrant" politics, showing how the school is basically a fascist meat grinder designed to weed out anyone with a conscience.
Some readers felt this part dragged. I get it. It’s a lot of classes and "will they/won't they" arguments between Violet and Xaden Riorson. But here’s the thing: that slow burn is necessary. You have to feel the walls closing in on Violet to understand why she eventually has to make the choices she does.
The Problem With Xaden and Violet
We have to talk about the communication—or the total lack of it. Iron Flame is famous for the "tell me everything" vs. "ask the right questions" loop. It’s frustrating. It’s meant to be. Xaden is keeping world-altering secrets because he’s literally leading a rebellion, and Violet is traumatized by a lifetime of her mother lying to her.
They’re toxic? Maybe. They're definitely messy. Yarros isn't writing a fairy tale; she’s writing two people in their early twenties trying to navigate a war while being magically tethered to dragons who also have their own opinions. Xaden’s need for "full disclosure" is a defense mechanism. Violet’s demand for "honesty" is a survival tactic. When those two things clash, it’s not pretty. But it feels human.
Expanding the World Beyond the Wards
Once the story breaks out of Basgiath, the scale of Iron Flame explodes. We finally see Aretia. We see the "fliers"—the gryphon riders who have been the "enemy" for centuries. This is where the world-building gets really meaty.
The magic system in the Empyrean series is tied to the land. Without the wards, the venin—soul-sucking magic users who turn the ground to ash—are unstoppable. Yarros introduces a lot of technical lore here. We’re talking about conduits, arrays, and the specific mechanics of how dragon fire creates the alloy needed to kill venin.
- The gryphon riders add a much-needed layer of perspective.
- They aren't just "other riders"; their magic is different, tied to the wind and the mind rather than raw elemental power.
- The tension between the dragon riders and fliers is palpable because it's based on generations of propaganda.
It’s not just about big battles. It’s about the realization that everything Violet was taught was a lie. The Navarrian government didn't just hide the war; they actively let people die to keep their own borders safe. That’s a heavy theme for a "romantasy" novel, and Yarros doesn't shy away from the ugly parts of it.
That Ending (And the Venin Problem)
Let’s talk about the final act. It’s a frantic, heart-pounding sequence that culminates in the Battle of Basgiath. The stakes are impossibly high. We lose characters we’ve grown to love. And then, there's the twist.
Xaden’s choice at the end of the book changes everything for the rest of the series. By turning—well, I won't spoil the exact mechanics for the three people who haven't finished it yet—he becomes the very thing he was fighting. It flips the dynamic of the series on its head. In Fourth Wing, Violet was the one who needed protecting. Now, she’s likely the only one who can save Xaden from himself.
The venin aren't just "monsters." They are a cautionary tale about what happens when you take more than you give. They are the ultimate environmental and moral antagonists.
Why Iron Flame Hits Differently
There’s a reason this book sold millions of copies in its first week. It’s not just the dragons (though Tairn’s sass is 90% of why I read these). It’s the way Rebecca Yarros handles disability and resilience.
Violet’s body is constantly failing her. She dislocates joints. She’s in pain. She has to wear specialized armor and use a custom saddle. In most fantasy, a "chosen one" would be magically healed. In Iron Flame, Violet stays disabled. She just learns to fight differently. She uses her mind, her speed, and her lightning. That representation matters more than the spicy scenes or the dragon lore combined.
The pacing is frantic. Sometimes it feels like you're sprinting through a forest at night—you're not quite sure where you're going, but you know you can't stop. That "Discover-worthy" hook is the emotional stakes. You aren't just reading about a war; you're reading about a girl trying to keep her soul intact while the world falls apart.

Critical Take: Is it Too Long?
Honestly? Yes. It’s over 600 pages, and you can feel it. There are subplots involving side characters that don't quite land, and the "secret revolution" logistics can get a bit bogged down in the middle.
However, the depth of the lore is what builds the foundation for the next three books. You need to know about the first six riders. You need to understand the wards. Without that "boring" stuff, the ending wouldn't have any weight. It’s a trade-off. Yarros is playing the long game here.
What You Should Do Before Reading Onyx Storm
If you’ve just finished Iron Flame and your brain is melted, you aren't alone. The wait for the third book, Onyx Storm, is the perfect time to go back and look for the clues you missed.
- Re-read the epigraphs. Every chapter starts with a snippet from a history book, a letter, or a manual. In Iron Flame, these are loaded with spoilers for the ending if you know what to look for. Specifically, pay attention to anything written by Jesinia or the "unauthorized" histories.
- Watch the dragons. Tairn and Sgaeyl know more than they're letting on. Their bond is the key to Xaden and Violet’s survival, but they are also keeping secrets from their riders.
- Map the venin sightings. There is a pattern to where the attacks are happening. It’s not random. The venin are looking for something specific, and it’s likely hidden right under the riders' noses at Basgiath.
Iron Flame isn't a perfect book, but it’s a gripping, emotional, and intensely ambitious sequel. It forces the characters to grow up in a hurry, and it forces the reader to question who the real heroes are. Whether you're in it for the political intrigue or the high-altitude dragon fights, the story of Violet Sorrengail is only getting started.
Actionable Insight: If you're struggling with the technical magic explanations in the middle of the book, don't sweat the small stuff. Focus on the character motivations. The "how" of the magic becomes much clearer during the final battle when everything is put into practice. If you are a writer yourself, study how Yarros uses Violet's physical limitations to create tension—it's a masterclass in "show, don't tell" for character vulnerability.
