Darkness Rises: (Yokai Book 3)

Not everyone is born to be a hero. Hikaru is satisfied with the simple life she leads in her quiet fishing village, but when the ocean's waters grow scarce with fish, she takes investigating into her own hands. She meets the legendary Guardian Seiryu who, despite his injuries, gives her a terribly dangerous gift.

She now possesses the ability to manipulate water. Magic is the talk of folklore, but she learns the truth of how real it can be when she inadvertently creates a small tsunami with a spike of her emotions. More crucially, it paints her as a target to those who thirst for such power.

Forced to flee from a usurper intent on uniting the land under one banner, Hikaru must choose her allies wisely. She seeks another Guardian, hoping they can remove the prime element's magic from her, but in doing so, she unknowingly shapes the future of all those around her.
