Witchbreaker - James Maxey - Bog

I am heir to an ancient and awesome power. You should not have betrayed me.
Sorrow was only twelve when her grandmother was hung for being a witch. She's spent every day since on a quest to become the most powerful witch who's ever lived, to seek revenge against the cruel church that's waged a centuries long war to wipe out witchcraft. Now, she's gained the ultimate power, stealing the magic of Rott, the Primal Dragon of death. Each time she taps into the magic, she loses a little more of her soul and body to the dragon. Can she win her war without losing her humanity?
