Ella Richardson's story about a bear struggling to fit in, beat off nearly 7,000 entries from budding authors around the country to win.
The "What's the Story?" competition run by Daybreak gave children a unique chance to create an illustrated book.
Ella, who told ITV Anglia she wrote the story in a matter of minutes, hopes that her message about bullying reaches out to everyone who reads her book.
She said "I still can't believe that out of 7,000 entries mine was chosen and that people will be able to read my story and hopefully get a message across about bullying."
Illustrator of children's classics including What The Ladybird Heard and The Princess and The Wizard Lydia Monks said: "Ella's story was a little bit different from all the others, that's why it grabbed me. She had created a whole new world. I loved the idea of Bee School, and the bear dressed up as a bee trying to fit in! As I read the story, the pictures popped into my head, which is always a good sign for an illustrator! It's got that lovely mix of humour and poignancy, that works so well in picture books. Well done Ella! I can't wait to start working on it. It's going to be a brilliant book!"
