Blood & Magic

It's the start of senior year and Kate is forced to deal with reality. She can't ignore her friends forever, but with problems at home and an unyielding magic inside of her, Kate is drawn to the one person she never liked--Nicholas Nightshade--the school's bad boy that everyone loves to hate--who has plenty of secrets of his own. 

There's a Supernatural World and Kate's a part of it. With her trauma bringing out the dark and light magic inside of her, she is forced to choose between two covens. One, practicing white and the other black magic, but nothing in their new-found world is ever straightforward. Kate is enlightened with an impossible truth--She and Nicholas didn't come together by accident and their being together will cause untold destruction. 
With an endless list of loved ones, the only way Kate can protect everyone she loves is to embrace the darkness that will swallow her whole. 

With students dying in freak accidents and two covens playing a tug of war with Nicholas and Kate's souls, nothing in her life will be the same again. 

... After all, all magic must be paid in blood.
