Rebecca Yarros is a #1 New York Times, USA Today, and Wall Street Journal bestselling American author born April 13, 1981. She is best known for the Empyrean series, which combines military romance with epic fantasy featuring telepathic dragons, starting with Fourth Wing in 2023. An Army spouse who began writing during her husband's deployments, Yarros draws from her military family experiences and has published over twenty novels. Her Empyrean series is being adapted into a television series by Amazon MGM Studios and Michael B. Jordan's Outlier Society.

Onyx Storm by Rebecca Yarros is perfect for fans of romantasy (romantic fantasy) who enjoy dragon-rider narratives, military academy settings, and slow-burn romance with high tension. Readers who loved Fourth Wing and Iron Flame will find essential continuation of Violet and Xaden's story, while those drawn to complex world-building, political intrigue, and powerful female protagonists will appreciate the depth. This book suits adults comfortable with mature themes, battle sequences, and emotionally intense relationship dynamics within an epic fantasy framework.

Onyx Storm by Rebecca Yarros is worth reading if you're invested in the Empyrean series, as it broke adult fiction sales records with 2.7 million copies sold in its first week. The novel delivers on promised political intrigue, new dragon lore, and character development while raising stakes considerably from Iron Flame. However, it's the third book in a planned five-book series, so starting with Fourth Wing is essential for understanding the complex plot, character relationships, and magical systems that underpin this installment's emotional impact.

In Onyx Storm by Rebecca Yarros, Violet Sorrengail desperately searches for a cure to save Xaden Riorson from fully turning venin while assigned to find the seventh dragon breed. Her journey takes her to the southern isles beyond the main continent, where she secures alliances, discovers the irids (seventh breed dragons), and reveals her second signet as a dream walker. Meanwhile, a powerful venin named Theophanie courts Violet to turn dark, and during a major venin attack on Aretia, Andarna breaks her bond with Violet to learn the ways of the irids.

Yes, you must read Fourth Wing and Iron Flame before Onyx Storm by Rebecca Yarros to understand the complex storyline, character relationships, and magical systems. Onyx Storm picks up after Xaden turns venin at the end of Iron Flame, with nearly eighteen months of backstory at Basgiath War College informing current events. The intricate world-building, political alliances between Navarre and Poromiel, dragon bonding mechanics, and Violet's first signet development are all established in previous books, making Onyx Storm nearly impossible to follow as a standalone entry.

Violet Sorrengail's second signet in Onyx Storm by Rebecca Yarros is dream walking, the ability to step into and manipulate others' dreams. Gifted by her dragon Andarna, this power is considered dangerously powerful because Violet can see into people's minds while they sleep and potentially influence them. The seventh breed dragons (irids) express concern about this signet's implications, though the full extent of dream walking's capabilities remains partially unexplored. This revelation adds another layer to Violet's already formidable lightning-wielding abilities.

Venin in Onyx Storm by Rebecca Yarros are dangerous dark magic wielders who drain life force and pose the primary threat to Navarre, Poromiel, and the dragon riders. When Xaden Riorson is forced to channel dark power, he turns venin but initially retains control without draining others. Venin can infiltrate societies disguised as ordinary people, wield stolen magical abilities like storm-wielding, and lose their humanity over time. The venin army's invasion drives the plot as Violet races to find a cure before Xaden completely loses his soul.

The seventh breed of dragons in Onyx Storm by Rebecca Yarros are called irids, discovered in the southern isles beyond the main continent where magic doesn't exist. Unlike the six known dragon breeds at Basgiath War College, irids are connected to Andarna's lineage and possess unique abilities including firing up wardstones to full functionality. However, irids disdain war and initially decline to help fight the venin army. Andarna ultimately breaks her bond with Violet to return to the irids and learn their ancient ways, creating significant emotional impact.

Onyx Storm by Rebecca Yarros expands beyond Basgiath War College's confines to explore new territories, alliances, and dragon breeds, whereas Fourth Wing focused on Violet's first year and Iron Flame on the revolution. The third installment raises political stakes with treaty negotiations between Navarre and Poromiel while deepening personal stakes as Xaden's venin transformation threatens his relationship with Violet. Reviewers note the darker tone signaled by the cover design, with less training academy structure and more high-stakes diplomatic missions, world-building exploration, and revelations about dragon lore.

The Empyrean series by Rebecca Yarros reading order is: Fourth Wing (2023), Iron Flame (2023), Onyx Storm (2025), with two additional books planned for a total of five novels. Fourth Wing introduces Violet Sorrengail at Basgiath War College and establishes the dragon-rider world, Iron Flame follows the revolution against Navarre's leadership and the venin threat, and Onyx Storm explores alliances and the seventh dragon breed. Reading in publication order is essential as each book builds directly on previous events, character development, and world-building complexity.
