Rebecca Yarros' Fourth Wing is one of the most popular romantasy books of all time. The first book of The Empyrean series burst on the scene in 2023. Just a few short years later, it's one of the most popular book series in the world.
We still have Book 4 of The Empyrean series on the way, along with the Fourth Wing TV series at Prime Video. Yarros also gave fans the first Empyrean novella, Threshing Day, and it was great to explore this world and these characters more.
While I love Fourth Wing, it definitely dominates the romantasy conversation in mainstream media, along with Sarah J. Maas' A Court of Thorns and Roses. I'm not saying Fourth Wing is overrated or anything like that; I'm a big fan! I just want to simply point out a few good romantasy series Fourth Wing fans should check out next.
If you're ready to read some other mega-popular romantasy book series, these are the books for you!
Fae and Alchemy by Callie Hart
First up, we have the Fae and Alchemy series by Callie Hart, which beings with Quicksilver, published in 2024. Like Fourth Wing, Quicksilver burst on the scene thanks to BookTok, and now, it's super popular. When you dive in, it's easy to see why.
Quicksilver tells the story of a young woman, Saeris Fane, who is not living the life of luxury. She's getting by as a thief. Everything changes when Saeris reveals incredible powers that open a portal of sorts to a Fae world far away from her own. With no friends and enemies all around, Saeris becomes close with Kingfisher, a legendary warrior. Not all is as it seems, though, in this story.
So far, there are two books in the Fae and Alchemy series. The second book, Brimstone, was released in 2025, and there's a third book on the way in, hopefully, 2027. If you like the enemies-to-lovers trope of Fourth Wing with a lot of Fae mixed in, this is the book series for you to read next.
Throne of Glass by Sarah J. Maas
Throne of Glass is my favorite book series on this list. It's not ACOTAR-level popular, but it's Sarah J. Maas' second-biggest series, and it's better than ACOTAR in some key ways. I don't want to get in a big back-and-forth about Throne of Glass vs. ACOTAR, but I really like this series!
Throne of Glass is an epic series that begins by following Celaena Sardothien, the most gifted assassin in the lands, after she is summoned to Adarlan to compete in a deadly competition to earn a position within the King's service. Over time, secrets are revealed and monsters enter the conversation. Everything you thought you knew the whole time was wrong. It's a brilliant story.
There are seven books, plus a few novellas, in the Throne of Glass series, and it's definitely a good time.
If you like the survival component of Fourth Wing and a protagonist who regularly takes on insurmountable tasks, Throne of Glass is the book series for you.
The Ashen by Demi Winters
The Ashen series is another one of my favorite romantasy series, and it's definitely one of the most underrated book series of the last few years or so. I don't know how more people don't know about this great story, and I'm making it one of my many missions in life to let everyone know.
The Ashen series begins with The Road of Bones, which was published in 2024. The Viking-inspired fantasy tells the story of Silla, a young woman who is on her own on the Road of Bones after her father was murdered. Silla falls in with a band of mercenaries on the way to their next job. Things take a dark turn as an adversary closes in on Silla, which puts her new crew in jeopardy.
That's just where this story begins. The Ashen series consists of three books so far, but there are at least two more on the way. Up next, you have Kingdom of Claw and Dawn of the North, the second and third books. Next year, Winters will publish Embers of Chaos, and then we'll hopefully get the fifth and final book the year after, but we'll just have to wait and see.
What I'm trying to say is that you have five books, plus a novella, set in this world to read!
Shepherd King duology by Rachel Gillig
Last but not least, we have another BookTok sensation to share. The Shepherd King duology by Rachel Gillig is definitely a book series I'd recommend to Fourth Wing fans. I can't remember if there are any dragons, but it's gothic romantasy like you've never read before.
The series begins with One Dark Window, which was published in 2022. It tells the story of Elspeth Spindle, a young woman who has a big secret, one that could upset the balance of the kingdom of Blunder. Elspeth falls in with a group of rebels trying to free the kingdom from tyranny. The series continues with Two Twisted Crowns, which completes the story.
There aren't that many similarities between Fourth Wing and One Dark Window, but there are some things about Elspeth and Violet that will be interesting for fans to observe. I will say, though, that the way that Violet communicates with Tairn is very similar to how Elspeth and the, well, thing in her head communicate. I really liked that aspect.
Overall, it's too hard to recommend one book series more than the other. It's really just a matter of personal taste. If I was reading them over again, I would probably start with Throne of Glass because it's a complete seven-book series, and it's so, so good.
I like all of these book series, though, and the fact that we still have more Fae and Alchemy books and The Ashen books on the way is super exciting. There's nothing better than catching up on a book series and being able to partake when the next book drops!
We'll share more news about The Empyrean series, the Fourth Wing TV series, and all these book series as we find out. Stay tuned!
