After defeating the Selador Sorceresses in the first volume of the Pelarian Multiverse Chronicle, 'Situation Vacant', Ruth Watson has now established herself as the Mage Prime of the Multiverse and is growing into her powers. She is driven to find a cure for her emotionally damaged son after the final battle with the Selador Sorceresses. But below the surface of the seemingly peaceful Multiverse a new threat is emerging. The Purity Movement, a fundamentalist sect dedicated to the removal and segregation of Talents is growing at an alarming rate throughout the Multiverse. When the movement gains access to the powers of Dreamwood they are ready to launch a form of evil into the parallels that threatens the survival of the Multiverse itself. Ruth and the Talents have to find new ways to deal with this threat. Magic alone is not enough.
