This little book is the first in a series of stories about Light. A short tale about a little honey mushroom who has just been born and is seeing the world for the first time. He has to find out what light is and how to find it in himself. How can you transmit light to others and share what you love. How you need to live to feel warm and safe even on the darkest night. After all, honey mushrooms glow in the darkness! This means that the light remains with them even at night. The book presents some scientific facts about light, which are explained simply, and will easily tell a child something about the world of physics. And also here there are a few words about God and about faith, about the meaning of life and existence, about the world and about feelings. Both young and adult readers will certainly be interested in the process of reading not only to observe the life of a baby mushroom on his very first day, but also to think about the structure of the world - the world around and the world inside.
