Little Zero 
LITTLE ZEROIs Nothing Really Nothing?
In the world where the numbers live,
Little Zero always sits a little to the side.
"You have nothing at all!" they laugh.
But when a tiny drop of light falls into Zero,
everyone discovers what was quietly there all along.

Six Questions to Talk About
There is no single right answer — and you don't need to ask them all. Just listen, slowly, to your child's own words.
- How do you think Little Zero felt at the beginning?
- Where do you think his feelings started to change?
- If you could meet Little Zero, what would you say to him?
- What do you think is hiding inside you?
- Is there something you'd like to try someday?
- If you took someone's hand, what could you do together?
Inside you, there are surely many, many lights. Let's find them — together with Little Zero.

THE AUTHORA word from the author
As a foster parent, I live with children. Some of them — like the child I once was — feel they have nothing inside. I wrote this story so that "zero" could mean something else: not emptiness, but a quiet place where everything begins.
The illustrations were created with generative AI. The story, composition, direction, character design and all creative decisions are the author's own.
