As others have noted, this book focuses on Stranger Danger, not mentioning adults who may be in or close to the family or in positions of authority. But within this sphere, it gets across the importance of wariness without being frightening. My four-year-old's asked to read it several times since the first introduction and asked good questions based upon the story, so it's probably best used as a good starting point for many conversations rather than expecting it to cover the gamut of important information.
