Onyx Storm by Rebecca Yarros (Paperback)

After nearly eighteen months at Basgiath War College, Violet Sorrengail knows there is no more time for lessons or hesitation. War has arrived, and danger is closing in from outside the walls and from within the ranks. With trust in short supply, every choice carries risk.

Violet must travel beyond the failing Aretian wards to seek allies in unfamiliar lands. The journey will test her wit, luck, and strength, yet she is willing to do whatever it takes to protect the people and dragons she loves. Along the way, she must also carry a secret so large it could destroy everything if it is revealed.

As the search for power, magic, and support grows more urgent, Violet is forced to confront the truth she alone can uncover. Her mission is not only about survival, but about finding the key that could change the course of the war and determine who can be trusted.

With enemies closing in and the storm gathering strength, Onyx Storm delivers a high-stakes struggle for loyalty, truth, and the future of Navarre.
