Morganville is already not the most pleasant place in the state of Texas, because vampires share power in it along with people. But in addition to the usual evil spirits, Bishop, an “old school” vampire, a native of ancient times, for whom no rules were written, appeared in the city. In addition, he is the father of Amelia, the local vampire queen, the all-powerful mistress of the city. And this uninvited guest, terrifying even the children of the night, announces a masquerade ball. Sixteen-year-old Claire, a student of the vampire Myrnin, a magician, inventor and... killer, who did not receive an invitation to the masquerade, realizes that the announced holiday is only a pretext for a decisive battle between Amelia and her father, and the future of the inhabitants of Morganville depends on whose victory it is. Therefore, she simply needs to infiltrate the vampire masquerade and intervene in the upcoming drama.
