Athena Townsend is no demon, but she isn't an angel, either.

After avenging her father's death, Athena is left with two choices - take a new job, or go to jail. It seemed like a no-brainer to take the mysterious Bryn Siegmund's job offer and work for the Valkyries Initiative, but things quickly get complicated.

As a Kidemonas, Athena is a guardian against an insatiable Soul Eater. Her magical talents are uniquely suited to fight spiritual predators, though she'll need a partner to watch her back. Unfortunately, her new boss seems to hate her, and Athena's new partner is none other than Sebastian Lawrence, the Shooter who legally assassinated her father, the Shooter who helped avenge her father's death... and the man who saved her life.

He's also the biggest asshole she'd ever met.

Sebastian is just as thrilled to be working with her again, but his wild magical talent might be a bigger threat to her than his uber-grump attitude.

For their first official assignment together, they have to track down the Unicorn, a teenage girl with an unprecedented healing ability - before the Spider's agent can find her first. When the signs of the Kidemonas' ancient enemy appear in the midst of their investigation, Athena will have to figure out how to unleash her full potential and trust Sebastian. Because if they can't work together, the world might not survive.

Save the Unicorn, defeat the Soul Eater, try not to murder her insanely hot partner. Just another day working for the Valkyries Initiative.
