Cursed Inquisitor by Kaitlyn Weiss

Eve Drake took a job as a web designer for a prestigious cosmetic firm, not realizing it would turn her quiet Canadian life upside down. Her unexpected acquisition of a mysterious item thrusts her into lethal peril, endangering her and her loved ones. The ominous Order deems her a Huntress, a bringer of evil into the world, and her executioner could be anyone—even the man she trusts. Bound to kill, yet compelled to protect her, Han desires her but cannot allow himself to be with her. He is dangerous, charismatic, in love, and convinced that she will be his undoing. But Eve is a strong woman, and in her hands, she has the power to turn even the direst circumstances to her advantage.
