Most fairy tales begin with "Once upon a time." This story does not, because it is not a fairy tale. It does not tell of an invented princess. This story is true, and everything you can read here really happened. I will tell you the story of Sisi. Perhaps you have already heard of her, or maybe you have seen a feature film or the animated series? Do you want to know what this princess was really like? Sisi, whose real name was Elisabeth and who later became Empress of Austria, was a fascinating woman who experienced a lot. That is what I want to tell you about. However, this book is not just for reading. There are a few things you can participate in yourself. The drawings in this book are seek-and-find images. In each picture, one of the diamond stars that Sisi sometimes wore in her hair is hidden. Additionally, you will find a game that takes you there.
