The Vision - Chronicles of the Ordained, #6

Beware, the destinies of the chosen have entwined, and ancient forces have awakened-there is no turning back from the path fate has woven. Trained to defend the innocent against a looming evil, Kela has never questioned her destiny. The enemy has never been in doubt, and her path is laid clear before her. Now, all is blurred by treachery and betrayal. Left with only one choice, she flees Yucca in search of the one known as Seilda the Tvopac, the Guardian of the Past, with an unwavering determination to step out of the shadows and into her rightful role. Having been cast into the world unprepared for her purpose, Kela is given visions to help her gain what has been lost.
But Kela quickly learns the secrets of the Past holds its own dangers. For ready or not, she is about to face the terror of her dreams-Asmeodai.
