Empyrean Series: Everything We Know About Book 4 & Beyond (April 2026)

Honestly, has any fantasy series grabbed the world quite like Rebecca Yarros's The Empyrean Series? From the moment Fourth Wing took flight, followed by Iron Flame and Onyx Storm, it's been a whirlwind. Readers everywhere, totally obsessed with Violet Sorrengail's wild ride through Basgiath War College and beyond, are always desperate for the slightest hint about what's next. We get it. As of April 2026, the buzz for Book 4 is definitely real, with Rebecca Yarros herself dropping some key updates on where this incredible dragon-riding saga is headed. Here at 4wing.com, we've gathered all the latest, verified info to keep you in the loop.

So, What's Happened in The Empyrean So Far?

Before we jump into Book 4 — and trust me, we're all itching to get there — let's quickly recap the wild ride that is The Empyrean Series. It all kicked off with Fourth Wing in May 2023. We met Violet Sorrengail, this seemingly delicate woman who, despite her mom's best efforts and every odd stacked against her, got shoved into the Rider's Quadrant. Talk about brutal! There, she faced life-or-death training, bonded with an epic dragon, and, of course, sparked that electric, complicated thing with Xaden Riorson. The book exploded, becoming a #1 New York Times bestseller and launching a massive global fanbase, thanks in no small part to "BookTok."

Just six months later, in November 2023, Iron Flame kept that momentum going. Violet found herself tangled even deeper in political games and a worsening war against the venin. Her powers grew, her loyalties got tested. That super-fast release schedule? Thrilling for us, sure, but it also showed the insane pressure Yarros was under.

Then came Onyx Storm, the third book, which dropped on January 21, 2025. This one, a true powerhouse, became the fastest-selling adult novel released in 20 years. And that ending? A major cliffhanger. We're all desperate for answers about Violet's future, the escalating conflict, and what's next for our favorite characters – especially Xaden Riorson, who, if you remember, turned venin at the end of Iron Flame. Onyx Storm saw an uneasy alliance forming between Navarre, Poromiel, and the Tyrrendor revolutionaries, all trying to fight off the venin army. Violet was frantically searching for a cure for Xaden, convinced the seventh breed of dragons, like Andarna, held the key.

Yeah, It's Five Books. You Heard That Right.

Okay, first things first, and this is probably the biggest sigh of relief for everyone: The Empyrean Series is, officially, a five-book saga. Rebecca Yarros has said it herself, more than once. That's huge! It means Violet's sprawling story, the deep complexities of this dragon-rider world, and the huge war against the venin will get the space they need. Think plenty of room for character arcs, shocking twists, and a truly satisfying ending. Knowing Onyx Storm wasn't the second-to-last book? That's relief. We still have two more books to look forward to, which promises a rich, expansive continuation.

Book 4: Where Are We Now? (April 2026)

After Onyx Storm came out, we all pretty much glued ourselves to Rebecca Yarros's social media, right? Scouring every post, every appearance for even the tiniest clue about Book 4. Well, here's the best news: it's official! Rebecca Yarros actually started writing Book 4 of The Empyrean Series in March 2026. She even made a big announcement about it on March 19, 2026, with an Instagram Reel showing her writing "#4" on a board. So cool. This came after some earlier hints in February 2026, when she posted a photo of her desk, complete with the first three books, notecards, and Sharpies, captioned, "Feels like a great day to start a stack of index cards." Yep, the plotting had begun. Back on January 24, 2026, she'd also told us on Instagram that once her contemporary novel was done, she'd be "back in the Empyrean world for the foreseeable future" and that "Book 4's playlist is simmering and I'm almost ready for the index cards and plot board."

This current progress follows a much-needed, deliberate break for Yarros. Remember those intense, back-to-back releases of Fourth Wing and Iron Flame? She made it super clear that pace wasn't happening again for Onyx Storm or future books. She openly said that accelerated schedule just wasn't sustainable for her mental or physical health, especially with her Ehlers-Danlos syndrome and POTS. So, after Onyx Storm dropped in January 2025, Yarros took time. She rested, hung out with her family, and even worked on a contemporary novel before diving back into Navarre's high-stakes world. This thoughtful approach means we might wait a bit longer, but it's all about making sure she's well and, in turn, that we get the best, most deeply crafted novels possible. We'll take it.

Title & Release Date: Don't Hold Your Breath (Just Kidding... Mostly)

So, yes, it's awesome that she's writing, but don't expect a title or a firm release date for Book 4 anytime soon. Rebecca Yarros does know the title, she's confirmed that, but she's keeping it under wraps for now. That's just cranking up the fan speculation, isn't it? Everyone's buzzing with theories.

As for when we'll actually get our hands on it? No official word yet. But given Yarros's new, much healthier writing pace, both fans and industry folks expect a much longer wait than that wild six months between Fourth Wing and Iron Flame. Onyx Storm landed about 14 months after Iron Flame, so we're probably looking at a similar, if not longer, timeline for Book 4. Frankly, late 2027 or even 2028 seems like a pretty realistic guess. Remember, publishing isn't just about writing. There's tons of editing, proofreading, cover design, marketing, distribution — all that takes a lot of time. So, we'll need to be patient. It's tough, I know, but this longer period is essential for Yarros to really deliver a polished, epic continuation of Violet's saga.

Dragon Whispers: What Yarros Has Teased for Book 4

Even though she's keeping the title and release date under wraps, Rebecca Yarros has dropped some pretty juicy hints about where Book 4 is headed. She's done it in interviews and fan chats. These little teasers have, predictably, sent the fanbase into a total frenzy, everyone trying to figure out what's coming for Violet and her crew.

Maybe the biggest, most gut-wrenching hint came during an Onyx Storm book tour event in L.A. back in January 2025. Yarros flat-out said, "Someone you love won't make it in book four." Given the series' body count, that's a heavy warning, and fans are already anxiously guessing which beloved character might bite the dust. Yarros even chillingly echoed it in a social media post: "Don't worry, everyone in Navarre is still alive. For now." Yeah. Those statements definitely signal some intense stakes and potential heartbreak ahead.

We also got more insight into Book 4's emotional core from Yarros's "plotting playlist" — a tool she uses while writing. A sneak peek included lyrics like, "Oh, I know that I can't live without you but this world will keep turning if you do would you even want me looking like a zombie?" Many of us are reading that as a direct nod to Xaden Riorson's scary condition after turning venin at the end of Iron Flame, and Violet's desperate hunt for a cure in Onyx Storm. It tells us that Xaden's struggle and Violet's fight to save him will stay a central, super emotional part of Book 4. We'll probably see the dark fallout of venin transformation and just how deep their bond truly goes. Remember that Onyx Storm cliffhanger? With an uneasy alliance forming against the venin and Violet seeking answers from the seventh breed of dragons? That absolutely sets the stage for all this.

Yarros also put our minds at ease, confirming she's "not really a fan of love triangles." So, while Violet and Xaden's romance will face challenges (let's be real, it always does), it won't be some messy third-party situation. But she quickly added, "Doesn't mean I'm not going to make them work for it, though." That implies plenty of continued struggles and obstacles for the couple. Honestly, with the war's perilous state, all the internal and external threats, and the sacrifices they're making, "working for it" is gonna involve immense emotional and physical tolls. No doubt about it.

Inside Yarros's Head: Her Writing Process & Philosophy

To really get a handle on The Empyrean Series' current pace and future, it helps to understand how Rebecca Yarros actually works. She's been super open about how unsustainable that initial, lightning-fast release schedule for Fourth Wing and Iron Flame was. She's putting her health first now, knowing that a slower, more intentional pace will ultimately give us a stronger, more carefully crafted story. That dedication to quality over speed? It totally shows her commitment to the series and us, her readers.

Yarros uses a pretty meticulous plotting process. She's often got index cards and plot boards going before she even starts writing. This organized method helps her keep tabs on the complex world-building, all those intricate plotlines, and the many character arcs that make The Empyrean Series what it is. Here's a fun fact: Yarros has also said she intentionally blocks Fourth Wing hashtags on social media. Why? To avoid fan theories. Her reason is pretty deep: she's known the whole story's path and its ending from day one. By shutting out outside noise, she makes sure her original vision stays pure, giving us the story she always planned. Even though she skips the theories, she loves seeing fan art and cosplays, really appreciating her community's creative energy.

She's also got a cool way of balancing her writing schedule, mixing fantasy with contemporary novels. She explained in an August 2025 comment, "I like to plot one project ahead, but I'm still in the thick of it with plotting the contemporary!" It's a smart strategy for her career, letting her jump between genres and keep her creative juices flowing before she dives back into the intense world of The Empyrean.

Not Just Books: The Empyrean TV Series Is Coming!

The Empyrean world isn't just living in the books, you know. Back in October 2023, Amazon MGM Studios announced they'd snatched up the rights to the whole series and are now developing a TV adaptation. And get this: Michael B. Jordan, the acclaimed actor and producer, is attached as a producer through his company, Outlier Society. Pretty cool!

Of course, making a huge fantasy series for TV takes time. But we've gotten a few updates. Originally, Moira Walley-Beckett was the showrunner, and Yarros even said she "loves the pilot script" Walley-Beckett wrote, believing it "captures what fans love about the series." Unfortunately, Walley-Beckett left the project in July 2025 for reasons we don't know. But by September 2025, Amazon MGM Studios had already found a new showrunner, which tells us the project is definitely still on track.

Then, in January 2026, Michael B. Jordan himself gave us an update, really stressing how dedicated they are to getting this adaptation right. He said, "We are making sure that this is going to be an exciting show that delivers on all of the things the fans want and some of the things that they won't be expecting either." He even added, "But trust me, I know how beloved this franchise IP is, and we're diligently… We're in the lab; we're cooking up. We got it. It's coming. It's early stages, but I feel how much people care about this one. It's not lost on us." These comments are super reassuring. It sounds like they're handling the adaptation with a ton of care and respect for the books, even if we don't have a TV series release date yet.

The Fandom Roars On (And On)

The sheer energy of The Empyrean fandom? It's undeniably a huge reason this series has blown up. From stunning fan art and killer cosplays to those intricate theories that pick apart every plot point and character's deepest motivations, this community keeps Navarre buzzing between books. Rebecca Yarros might intentionally dodge fan theories (she wants to keep her narrative vision pure, after all), but she absolutely loves seeing the creative fire and passion her stories spark.

That wait for Book 4? Yeah, it might be a long one, but honestly, it's a shared journey for millions of us. We're all in this together. Discussions about wild plot twists, what Yarros's subtle hints really mean, and the ultimate destinies of characters like Violet and Xaden are thriving everywhere — BookTok, Reddit, and right here on fan forums like 4wing.com. This collective anticipation just underscores The Empyrean Series' massive cultural footprint. And you know what? When those next official announcements finally drop, this community will be more than ready to embrace them. Wings wide open.

What's Next for Navarre (And Us)

So, here we are in April 2026, and the future of Rebecca Yarros's The Empyrean Series is definitely starting to come into focus, even if it's moving at a more deliberate speed. We can all cheer for the official news: Book 4 is being written! That's a huge step after Onyx Storm. With five books planned in total, we're set for a truly epic and complete conclusion to Violet Sorrengail's journey. No title or release date for Book 4 just yet, but the hints about character fates and Xaden's ongoing venin fight have only cranked up the anticipation.

Yarros is prioritizing her health and the quality of her storytelling, which means we might wait longer, but we'll get meticulously crafted novels. That's a trade-off I think most of us can live with. Plus, with the Amazon MGM Studios TV adaptation steadily moving forward, The Empyrean Series just keeps growing and grabbing new fans. For now, we've gotta hold tight, patiently waiting for Rebecca Yarros to drop the next official updates. Because let's be real, the dragons of Navarre? They're still very much soaring.
