Fourth Wing is a new adultfantasy romance novel written by the American author Rebecca Yarros. It is the first book in the Empyrean series,[1] following the journey of Violet Sorrengail, who is forced by her mother, General Sorrengail, to join the Basgiath War College and become a dragon rider in the kingdom of Navarre. Even though she has been trained her entire life to enter the Scribe Quadrant, Violet must endure deadly quests and competitions that push her to her limits while trying to avoid being killed by one of the most powerful riders in the quadrant, Xaden Riorson.
The book was published in the United States on May 2, 2023, by Red Tower Book, an imprint of Entangled Publishing. Its viral success within TikTok's reader community, BookTok, significantly contributed to its No. 1 ranking on The New York Times bestseller list. It won The International Book of the Year 2024 at the annual TikTok Book Awards. The book sold over 2.7 million copies in its first week and has been translated into approximately 30 languages.[2]
Yarros has mentioned in interviews that the idea for Fourth Wing emerged when her publisher announced that they were going to start a romantic fantasy line, prompting her to submit five proposals. After several reviews, her publisher selected the third idea, which explored the Empyrean world.[3] The inspiration for the story stems from her fascination with dragons, her military experience with her husband, and her personal struggles.[3] Violet's physical fragility, as described in the book, was influenced by Yarros's own experience living with Ehlers-Danlos syndrome, a genetic disorder affecting both her and her children. Yarros has expressed a desire to represent people with chronic illnesses, showcasing that they can also be heroic.[4]
20-year old Violet Sorrengail is the youngest daughter of General Lilith Sorrengail, who leads the Basgiath War College in Navarre. Despite having trained to be a scribe like her late father, and suffering from chronic pain and weak joints, Violet's mother orders her to join the Riders Quadrant. Violet's older sister, Mira, a dragon rider graduate, gives Violet an unbreakable corset made of dragon scales from her dragon Teine. Many of the Riders' parents were involved in the rebellion years earlier, which was put down by General Sorrengail. As punishment for their parents' rebellion, these cadets are branded with relics and forced to enter the Rider Quadrant. Mira warns Violet that the 'marked ones' hold a grudge against their family and may seek revenge on her.
Students can choose to join one of four military branches: Infantry, Healer, Scribe, or Rider. Riders bond to a dragon which allows them to develop a magical power known as a signet. Upon entering the War College, Violet is nearly thrown to her death by violent cadet Jack Barlowe, who vows to kill her. She meets Xaden Riorson, a third-year student with a rebellion relic whose father was executed by General Sorrengail. In Basgiath, Violet reunites with her childhood friend and longtime crush Dain Aetos, a second-year cadet. Violet joins Fourth Wing under Xaden's command, with Dain as their squad leader.
When cadet training starts, Violet struggles with sparring because of her frailty. She is targeted by marked ones, who blame her for General Sorrengail's actions. She begins learning her sparring partners' names in advance and poisoning them to give herself the upper hand. One night, she overhears the marked ones having a secret meeting and is caught by Xaden, who asks her to stay quiet in exchange for a favor in the future. In a sparring match later, Xaden shows her how to improve her fighting skills.
Violet and her squad meet the dragons and see a rare golden feathertail, a species known for avoiding humans. Jack wants to kill the golden dragon, thinking it is weak. Violet intervenes, but Jack and his friends attack her. Violet defeats her attackers, and then Tairn, a large black dragon, appears, kills the remaining students, bonds with Violet, and takes her back to school. Violet also connects with the golden dragon, Andarna, and becomes the first rider with two dragons. Dain kisses Violet, but finds that she no longer has feelings for him.
Violet struggles to maintain balance on Tairn during flying training. One night, Tairn wakes her when six cadets attempt to kill her. Xaden rescues her and kills the cadets, and when Violet reveals a senior cadet let the attackers in, Xaden confronts them and has them executed. After the attack, Xaden arranges for Liam, his foster brother and a marked first year cadet, to protect Violet. During a meeting with their dragons, Violet learns she can communicate with Sgaeyl because of her bond with Tairn. She kisses Xaden due to Tairn's feelings for Sgaeyl, which influence their feelings as well. During a sparring session, Jack tries to kill her, and she escapes by forcing orange juice into his mouth, triggering an allergic reaction.
Violet and Xaden find they can communicate telepathically through their dragons. Later, during a capture-the-flag game, Violet uses Andarna to freeze time, saving Liam from Jack, and manifests the rare and powerful signet to wield lightning, which she uses to cause a landslide which seemingly kills Jack. That night, Violet and Xaden become intimate. She asks why he and his cousin Bodhi were out after curfew. Xaden shares they were at a nearby military base but does not explain further.
In the final round of the college War Games, Xaden leads a group of marked ones to an outpost in Athebyne, where they encounter gryphon fliers. Violet learns that Xaden has been secretly supplying weapons to them. Xaden reveals that Poromiel is under attack by venins, creatures thought to be mythical. The leaders of Navarre are concealing this from their people. They arrive at the outpost but find it deserted. A nearby village is attacked by venin and wyvern and they realize they have been lead into a trap by Colonel Aetos, who found out about their trips to Athebyne through Dain using his signet on Violet without her knowing.
Despite the danger, Violet and her crew help the gryphon fliers against the venin attack. Xaden's younger brother Liam and his dragon are killed. Using her lightning powers, Violet defeats the last venin and briefly stops time with energy from Andarna, but she becomes seriously injured. Xaden and the survivors seek safety in Aretia, an abandoned city. After three days, Violet wakes up, and Xaden vows to earn back her trust.

Reception
The book had a mostly positive critical reception. Publishers Weekly gave the book a starred review, praising its worldbuilding, characters, and "sexy dark academia aesthetic".[5] Alana Joli Abbott, in a review for Paste, praised its use of familiar tropes and compared it favorably to fantasy series like Blood Trials by N.E. Davenport and A Court of Thorns and Roses by Sarah J. Maas.[6] The book was one of the most borrowed titles in American public libraries during 2023 and 2024.[7]
Fourth Wing became a viral phenomenon on BookTok, where the hashtags "#FourthWing" and "#RebeccaYarros" have more than a billion views combined. Its popularity led it to reach No. 1 on Amazon's bestseller list as well as the No. 1 spot on The New York Times Bestseller list, where it stayed for 18 weeks.[8][9] It has been credited as helping to popularize the "romantasy" genre, which blends elements of romance and fantasy genres.[10]
Kimberly Terasaki of The Mary Sue wrote about a phenomenon within the fandom of portraying Xaden, a primary love interest of the protagonist, as white in fan art despite the fact that he is described as dark-skinned in the book. Yarros also commented on the phenomenon and asserted that the character is not intended to be white.[11]
There is a review available by Tamara Saarinen from the School Library Journal, who approached Fourth Wing from the perspective of a school library. She noted that the use of modern profanity and sexual scenes make this book more appropriate for older teen audiences. That said, she did give an overall positive verdict for school libraries, claiming it would attract “romantasy” fans.[12]
The sequel, Iron Flame, was released on November 7, 2023.[9][13] The third book, Onyx Storm, was released on January 21, 2025.[14]

In October 2023, Variety reported that a television adaptation of the series was in the works at Amazon MGM Studios.

Jac Schaeffer was in talks to replace her before Meredith Averill was announced to be the new showrunner.[16][17][18]
In March 2025, Yarros announced graphic-novel adaptations are in the works for all three of books of The Empyrean series (Fourth Wing, Iron Flame, and Onyx Storm). Yarros has stated she will be adapting the text herself along with a team of comic creators. A total of six graphic-novels are planned to span all three books. This project is in partnership with Ten Speed Graphic, Piatkus, and Entangled Publishing. Release dates have not been announced.[19]
