Fourth Wing Series Order: The Complete Empyrean Reading Guide

There are currently three published books in the Empyrean series, with a fourth expected. The reading order is strict. Do not skip around. Do not start with Iron Flame because someone told you it's better. The character arcs and plot twists are cumulative, and later books assume you remember specific details from earlier ones.

Here's the order:

1. 1.Fourth Wing (April 2023)
2. 2.Iron Flame (November 2023)
3. 3.Onyx Storm (January 2025)
4. 4.Untitled Book 4 (date not announced yet)

Yarros has confirmed the series will be at least five books. The exact number hasn't been locked, but the story she's telling requires more room than a trilogy. Each book covers roughly one academic year at Basgiath War College, though the scope expands significantly after the first installment.

Violet Sorrengail was supposed to be a scribe. Small, hypermobile, with a body that bruises easily and bones that break when they shouldn't. Her mother, General Sorrengail, decides Violet belongs in the Riders Quadrant instead, where cadets bond with dragons or die trying. The survival rate is genuinely terrible.

The academy setup works because Yarros commits to the danger. People die in training. The dragons are not pets. They're sentient, opinionated predators who choose their riders based on criteria that nobody fully understands. Violet's physical limitations force her to approach every challenge differently than her peers, which keeps the underdog arc from feeling formulaic.

Then there's Xaden Riorson. Son of a rebel leader, marked as a traitor's child, assigned to Violet's wing specifically to make her life harder. The enemies-to-lovers dynamic between them is the engine of the book. They don't like each other. The attraction builds through forced proximity, shared danger, and a grudging respect that neither of them wants to feel. By the time the romance kicks in, you've earned it.

The twist at the end reframes the entire political situation at Basgiath. It's the kind of reveal that makes you want to immediately re-read the first hundred pages with new eyes.

If Fourth Wing was about surviving school, Iron Flame is about surviving a war nobody will admit is happening. Violet knows the truth about what's beyond the wards now, and so does Xaden. The problem is that the leadership at Basgiath either doesn't believe them or doesn't care.

The scope expands dramatically. New locations, new factions, new political pressures. Violet's relationship with Xaden gets more complicated because trust issues don't evaporate just because you're in love with someone. He keeps secrets. She pushes for transparency. Both of them have valid reasons for their positions, which makes their conflicts feel real rather than manufactured for drama.

The dragon lore deepens. Yarros introduces new elements of the bond between riders and dragons that raise the stakes for everyone involved. The magic system, which felt relatively contained in the first book, opens up in ways that suggest the series is building toward something much bigger.

Iron Flame is longer than Fourth Wing and some readers feel the pacing sags in the middle act. That's a fair criticism. But the back third is relentless, and the ending hits harder than the first book's twist. Yarros is not afraid to put her characters through genuine pain.

Onyx Storm is the book that split the fandom. Not because it's bad. Because it's different. The tone shifts darker. The romance recedes from the foreground. The political and military plotlines take over, and Violet spends significant portions of the book dealing with consequences rather than charging forward.

This is the book where Yarros proves the Empyrean isn't just a romance series with fantasy elements. It's a fantasy series with romance elements. The distinction matters. Readers who came for Violet and Xaden's relationship felt the absence. Readers who came for the world-building and political intrigue felt rewarded. Both reactions are valid.

The ending is devastating. Not a cliffhanger in the traditional sense, but a series of revelations that fundamentally change what the remaining books need to accomplish. Characters you trusted turn out to have been playing longer games than anyone suspected. The scope of the threat becomes clear, and it's bigger than anyone at Basgiath prepared for.

If you're re-reading before Book 4, pay close attention to every conversation about the wards, the venin, and the history of Navarre. Yarros seeded details across all three books that only become visible on a second pass.

Amazon Prime Video is developing the Empyrean series as a television show. Meredith Averill is attached as showrunner. Rebecca Yarros and Liz Pelletier are executive producing. Amazon acquired rights to the entire series, not just the first book, which signals they're planning a multi-season run.

In October 2026, Deadline reported that Esther McGregor will play Violet and Emilio Sakraya will play Xaden. There is still no premiere date. Our Fourth Wing TV show guide tracks the cast and production news as it lands.

The adaptation faces the same challenge every book-to-screen romantasy does: how much of the internal monologue can you translate visually? Violet's perspective drives the books. Her observations about other characters, her strategic thinking during battles, her internal reactions to Xaden. Losing that interiority would change the feel significantly.

The dragon sequences will be expensive. The Riders Quadrant scenes require a visual scale that's hard to achieve on a TV budget. But Amazon has shown with other fantasy properties that they're willing to invest when the source material has a built-in audience, and the Empyrean has one of the largest built-in audiences in modern fantasy.

This is also happening alongside the Everflame Hulu adaptation and the Shield of Sparrows Amazon MGM film. 2026 is the year romantasy went to Hollywood.

If you've finished Onyx Storm and need something to fill the gap before Book 4, these books share specific DNA with the Empyrean.

Spark of the Everflame by Penn Cole has the same indie-to-massive trajectory that Fourth Wing had. A mortal woman forced into an immortal world, slow-burn romance with genuine antagonism, and political stakes that escalate across the series. The Kindred's Curse Saga is heading to Hulu, so you can get in before the adaptation.

The Serpent and the Wings of Night is the closest match for readers who want the deadly competition dynamic. Oraya is a human raised among vampires, entering a tournament where she's the most vulnerable participant. The romance with Raihn builds through forced alliance and mutual survival. If Violet's underdog energy hooked you, Oraya's will do the same.

When the Moon Hatched by Sarah A. Parker is for readers who want more dragons. The Moonfall series puts dragon-bonded characters at the center of a story about grief, rage, and a love that spans lifetimes. The sequel, The Ballad of Falling Dragons, drops May 19, 2026.

An Ember in the Ashes by Sabaa Tahir takes the military academy setting and makes it darker. Laia infiltrates a brutal training institution as a spy. The romance is forbidden and builds across four books. If you loved Basgiath's danger but wanted more political resistance, this series delivers.

Throne of Glass by Sarah J. Maas is the obvious comp for readers who haven't gone there yet. An assassin in a deadly competition, a slow-burn romance that evolves across the series, and a world that expands dramatically from where it starts. Maas wrote the template that Yarros built on.
