Katerina Walter lived her entire life thinking she was normal. She grew up in a normal home, with normal parents, she attended a normal school and she had normal friends. Until one day, on her thirteenth birthday, she receives a letter that reveals that everything she thought she knew about her life was a lie. Katerina realises that the normal parents she thought she had, weren't her parents at all, and they were not normal. The normal home that she had grown up in was not at all what she once thought it was, and there were many secrets hidden beyond the walls, including the fact that she has a twin brother. Within the letter, it is unveiled that past all of the regular people, and behind the plain schools, there is a world of magic, just waiting to be explored.
