Dark agents. Book one, Violet and the trial of trauma
(Graphic Novel)

"Meet Violet -- a young witch whose parents were murdered by a necromancer when she was a child. Running from country to country, as well as from herself, Violet never gets a chance to fully process her traumatic experience. Then, at age 19, her life takes a dramatic turn. Violet begins training at the Underworld Intelligence Agency in hopes of becoming a Dark Agent -- someone tasked with keeping the balance between the world of the living and the world of the undead. As she battles monsters and ghouls, Violet learns to conquer her inner demons as well. Blended seamlessly throughout the story are elements of a powerful treatment called acceptance and commitment therapy (ACT). Whether or not you've experienced a traumatic event like Violet, you'll find real skills you can apply to your own life to help you hone your unique superpowers." -- From back cover.
