Astrid has already been six years old. Today is her birthday. She’s the most ordinary girl who lives with her parents in an estate by the shore of the Rainbow Bay—in the most amazing country in the world, Mysteria. It’s a land of magicians, and everyone in it is a magician, and Astrid’s father is also a magician. But her mother isn’t a magician, because Astrid’s mother is a demon. And Astrid is also a demon, but that’s no big deal—she’s still the most ordinary girl, and today is her birthday. And tomorrow Astrid will go to school, like all other ordinary children.
