Breath of Starlight. Nine Rivers Odyssey, #1

He was forged for war. She was born from the stars. Neither is ready for what waking her will unleash. When the immortal Resh'Agar finds Auryn imprisoned in ancient ice, her awakening reshapes more than just the battlefield. Her quiet strength, her unfathomable magic, and the way she looks at him, as if she sees the man beneath the monster, upends everything he has sworn to be. But Auryn's arrival does not go unnoticed.
As whispers of her power spread, old forces stir, alliances fracture, and the sky itself begins to split. Rifts yawn open, swallowing sunlight. Creatures long forgotten drag themselves into the world of the living. To survive, the Resh'Agar and Auryn must flee into the wilds together before the rising darkness devours them both.
