Curses and Crimes. All the Queen's Knaves, #2

"No witch shall live among those who hold to God's will. They shall be cast out, lest they bring corruption to all."Nightingale Goodweather has a secret. Ten years ago, Gale and her brother Hawk were abandoned in the woods as their village starved. They returned as heroes, children used by God to slay the witch who had cursed their land. But Gale has never felt like a hero, and since her return she's kept a dark secret: during her time with the witch she allowed magic to corrupt her soul.
She's never wavered from her vow to turn her back on that tempting power. But when a new curse arises, spreading sickness and death, Gale realizes she'll need to stretch the limits of her faith and defy the laws of the land to fight magic with magic. If she wants to save her people and become the hero she's always wished to be, she'll have to risk her soul and her life. and enlist the help of the last person in the world she ever wished to speak to again.---CONTENT NOTE: please be advised that this story contains scenes involving deaths of characters of all ages, gore, and religious indoctrination
