Elsie True lives with only one goal in mind …
… to avenge her father's death.
Branded a traitor among the brotherhood of the Cause, an organization dedicated to the destruction of all magical creatures, her father was unjustly murdered for falling in love with a celestial being, leaving a teenage Elsie to learn the creature-hunting business with the help of her father's old friend.
Her life revolves around besting the Cause and keeping the world safe from any creatures that get out of hand. When her mentor signs her up for another case, she jumps at the opportunity to steer business away from the corrupt organization.
Not long into the investigation, she realizes she might have walked right into a setup, including coming face-to-face with a creature she doesn't know if she should kill or protect.
Elsie feared little in life, but she isn't prepared to face the demons of her past, especially those hell-bent on killing her. Outwitting her enemies means solving the case, but in a world where she has more foes than friends, who can she trust?
