The Diary of the Missing Sister

Each book in the series about the mysteries and secrets of Rookwood School becomes an international bestseller. This story is both a detective tale and an adventure, an exciting quest—a complete set of plot twists that make the book unforgettable. The main characters, Scarlett and Ivy, are mirror twins, identical in every way except for their names and personalities. That's why it's so interesting to see how they substitute for each other and how they behave differently in the same circumstances.

This book shows how important sincerity and trust are, especially in those moments when it seems that one cannot trust anyone. It's also a cool story about how, despite all obstacles, with the help of friends, one's own courage, and resourcefulness, one can overcome a very strong and influential opponent.
