Onyx Storm Summary

After the events of Iron Flame, the kingdoms of Navarre, Poromiel, and Tyrrendor form a fragile alliance against the invading venin army. This dangerous enemy threatens their lands, forcing the leaders to work together, even as tensions simmer. In this environment, Violet Sorrengail is desperate to save Xaden Riorson, who has become venin yet struggles to control his dark powers. She believes that finding the elusive seventh breed of dragons holds the key to his salvation.

Violet’s urgency grows when Jack Barlowe, another venin, warns her that Xaden will soon lose control, putting her at risk. To protect this knowledge, she enlists her friend Imogen to erase Jack’s memory, limiting the threat he poses. Amid these challenges, Nararre faces relentless storms due to the absence of General Sorrengail. These weather conditions complicate political talks with Poromiel, highlighting the seriousness of their situation.

At Basgiath keep, Violet and her allies, Rhiannon and Ridoc, fend off a venin infiltration while guarding Jack’s prison cell. During this encounter, Violet meets a mysterious silver-haired woman named Theophanie, who seems to share storm-wielding powers with General Sorrengail. Theophanie vanishes just as quickly, leaving Violet to wrestle with her mission to unearth the seventh dragon breed. Captain Grady supports her efforts, focusing on securing their alliance.

As pressure mounts from Viscount Tecarus, Violet pushes forward to finalize their demands with Poromiel’s powerful gryphon fliers. Her group commits an act of treason by altering a wardstone, allowing gryphon fliers to channel lesser magics inside the wards. This win for the alliance comes at a risk, and as punishment, she and her team are assigned to the Samara outpost. They disobey orders to defend a nearby town from a surprise venin attack, encountering Theophanie once again in the chaos.

In the midst of rising conflict, Theophanie exposes herself as a powerful storm wielder, engaging Violet in fierce battle while venin wreak havoc in the city. As the chaos unfolds, Rhiannon and Imogen tackle a wyvern under control of the venin. The battle proves devastating, with casualties like Imogen’s friend Quinn strengthening the stakes for everyone involved.

Violet and Tairn pursue Theophanie and her wyvern, but are caught in a trap, plummeting toward the ground. As Violet loses her dagger, she remembers a special gift from Aaric: a marble dagger from the high priestess of Dunne, given with instructions for times of need. She recognizes Aaric's signet allows him to foresee events, realizing the importance of her situation.

In the darkness of cascading shadows, Violet suspects that Xaden has tapped into his powers to safeguard the city. Overwhelmed by emotion, she professes her love for him, infusing hope into their bond. With this support, she unites with Andarna, the seventh dragon, racing to defeat Theophanie before collapsing from the effort.

Shifting to Xaden’s viewpoint, he grapples with his venin nature and leans toward a self-sacrificial choice to save Violet and Sgaeyl. Just before he completely surrenders, Violet's declaration of love gives him clarity. In this decisive moment, he learns of another enemy among his closest, but he

In the climax of Onyx Storm, Violet fights valiantly against the venin dark wielders to save her sister Mira and protect Draithus. With Aaric's help, she triumphs over Theophanie, but the victory comes at a cost. Xaden channels an onyx storm, saving them both, but he transforms fully into a venin; his love for Violet leaves a fragment of his soul behind.

As the story concludes, Violet awakens in Riorson House, struggling with amnesia regarding the past 12 hours. Shockingly, she discovers she has married Xaden, who has mysteriously vanished. He leaves a note with the stark warning: "Don’t look for me. It’s yours now," hinting at deeper troubles. Furthermore, Imogen has wiped her memories of the time spent with Xaden.

Complications grow as Violet grapples with the aftermath: several deaths among humans and dragons, six missing dragon eggs, and Xaden facing blame for the chaos. Four riders, including Garrick, are also unaccounted for, heightening the mystery surrounding their fate and the stolen eggs. Violet now faces a fractured world, torn by love and loss, setting a dramatic scene for the series to continue.
