Charmed — Lindy Zart

On the day Taryn turns eighteen her life changes. A black-eyed man with a chilly aura accosts her and she's abducted by a man who really isn't a man, but a Manang; a half-man, half-angel. She's told she's someone special; a Charmed, and the key to winning in a battle of worlds about to collide. Only problem is, she can be a weapon of good or a weapon of bad, depending on who gets to her first.
