18-year-old Ern is terrified. The vampires are making a turn back to her village. They are silently usurping villages across the world, with the intentions of seizing the Sisters of Elements. And she is supposedly one of them. Her mother, as most people told her, Veronica, was taken away five years ago, accused of being the mother of Luna, the Moon Goddess. Now, all Ern wants to do is to take revenge on the vampires. But the vampires are as hypnotizing as their castle, particularly one person, Ern's supposed founder, Gavron. Now, there is a problem. A ritual that needs to be solved. Or risk perishing with all of humanity...
