Anna Walker signs a children's book that concerns us all. How many times have you felt that everything around you is gray, even if the sun is shining in the sky? Especially if you are a small child and have no idea how to deal with it.

This is exactly what happens in the life of little Billy, who feels that something follows him everywhere and makes everything seem so difficult. Mr. Uff is there. Silent and omnipresent. Even in the most special moments…

But how will Billy manage to reconcile with his follower and ultimately overcome the burden he feels inside? The story provides the solution, just like life itself. The book is intended for readers over 4 years old.
