A conspiracy against the crown turned into the father’s death for her, and for her it meant expulsion from a girls’ boarding school and accusations of treason against the Old Russian Empire. The conspiracy against the crown became a challenge for him—finding the traitor isn’t the hardest part, because his own life and the life of the young heiress of an old count are on the line. Only one week remains until the first Peterhof ball, and within that time the head official of a special cabinet must find the guilty ones—either confirming or refuting the accusations against the alchemist’s daughter. From that day on, they must together uncover the identity of the conspirator, learn whose ancient blood has awakened the gift of necromancy in the bearer, and prevent a rebellion in the streets of Peterhof. Even though there’s only a week left, together Lord Levshin and the young Olga will try to deal with the task. But will the feelings awakening in them—so untimely—won’t they get in the way?
