Ulrich loves numbers. He can always rely on them. A math problem can never go one way or the other. Changing schools after a move is a completely different story. That can go either way. And when Uli is supposed to introduce himself to his new classmates, all that comes out of his mouth in his excitement is a stuttered "U-U-Uhu." It's no surprise that everyone laughs at him, and he becomes known as just the "Uhu" among his new classmates. Who wants a Uhu as a friend? Uli becomes quieter and quieter. No one really notices him anymore. Until Ulrike joins the class. She sees him just as he is. And she is not quiet! Astrid Frank has created an authentic, winning character in Uli Unsichtbar, whose thoughts and number games young readers can easily immerse themselves in. A sensitive, child-friendly, and solution-oriented portrayal of what truly matters.
