Onyx Storm By Rebecca Yarros

The sky darkens. The storm breaks. In the spellbinding third installment of the bestselling Empyrean series, alliances shatter, loyalties are tested, and a forbidden power rises that could save—or destroy—the world. With her dragon bond unstable and war raging across the realms, [Main Character's Name] must master the volatile onyx magic that surges within her before it consumes her utterly. Torn between her duty to the Empyrean order and her heart's forbidden desire for the enemy prince, she embarks on a perilous quest into the heart of the long-lost Storm Kingdom. There, she will uncover ancient secrets that rewrite everything she knows about dragons, magic, and her own destiny. Brimming with breathtaking aerial battles, devastating betrayals, and slow-burn romance that burns hotter than dragonfire, Onyx Storm is an unputdownable epic for fans of Fourth Wing, The Priory of the Orange Tree, and A Court of Thorns and Roses.
