A Balance of Power - Nicole Zoltack - Bog

It's not every day you accidentally open a portal to Hell on earth. A witch died to bring Crystal Wynter into the world as the embodiment of magic in the teenager's first life. Now, that witch is back with a vengeance. Unfortunately, Crystal's attempts to free herself from the witch's clutches have disastrous consequences. Demons are hell-bent on destroying her hometown Claymore. Throughout her second life, Crystal has lacked magic except for the ability to shift into a creature and a strange connection to both life and death. If she can't find a way to balance her new powers, the apocalypse will happen this time. Magic has never been more vital.
