The magical barrier known as the Veil is all that stands between our reality and the Otherworld. Those with the gift of magic can pull energy through it to perform miraculous feats of power. The Inquisitio opposes these mages, who have organized themselves within the Society for Psychical Defense. The world of magic is shaken by the awakening of a wild mage, a woman capable of manipulating the Veil itself. She has the power to either eradicate the Inquisitio or rob the mages of their abilities. Only one side can win and it will be the side that gets to the wild mage first.
What do you do when a mage tells you to jump? When you’re a painfully shy teenager, you ask how high. That’s how Claire Mitchell ends up a pawn in a war that is far beyond her understanding. She's stuck in London while she shareds her body with the spirit of the long-deceased medium Madame Petrovna Stravinsky. The only support she has in her new life is Alena Senna, her attendant, whose job it is to keep Claire’s body and mind in one piece during the course of her servitude.
Claire is only supposed to be with the Society for a few months, but in love and war, all bets are off the table. Plans change and Madame Stravinsky decides to keep Claire’s body as her own. Claire is stuck beyond the Veil between the world, and the war escalates around her. She is forced to put her faith in Alena, but in order to help Claire, Alena will have to break with the only family she has and expose Claire's body to more danger than it might be able to survive.
