The Elementalist Elf is the Chosen One

For centuries the elves have lived in the shadow of an ancient power, hidden from those who believe them to be extinct. But now their survival seems to be in the hands of an eighteen year old elf named Kino. Endowed with the power to command the very elements, she has been proclaimed as the Chosen One destined to protect her people from mankind. Yet with an ancient threat rising, the fate of the elves may be decided by something more than just powers bestowed upon her. Beyond the borders of her homeland lies a world more treacherous than any legend has ever told. A world that Kino is about to discover isn't what it seems.
