The book starts with an educational piece about the subject. Here you will also immediately encounter the cardboard flashlight. Then a story begins with bold words. These bold words are depicted at the bottom of the page. The right page is still dark, but if you place the flashlight behind it, a beam of light is created, just like the real thing! With the flashlight you can search together for the bold words depicted. This way you can read a book together interactively. There are multiple themes available in this series!
