A mysterious messenger delivered to the master of the Kabbalah, Sabian Blake, a gift he could never have dreamed of—the great book Nemorensis, not intended for human eyes. The scientist finds a terrible prediction on the pages of the book: “Wormwood... a shining star will fall from heaven... and many will die from its bitterness.” Since then, Blake has searched every corner of the sky in search of a star, hoping to see a harbinger of the era of the triumph of human reason. But the approach of a comet brings not light and intelligence, but death and destruction. Blake's young maid named Ajetta dared to steal "Nemorensis" and became a pawn in a dangerous game, the participants of which are not only mere mortals... If the prophecy comes true and the star Wormwood falls, evil forces will be able to be reborn in a new guise. The hope for saving this world is illusory. But it’s not for nothing that the fallen angel Tegatus became Adjetta’s companion, because the Universe was created not for evil, but for love.
