Take Mal Peet. His amazing football book Keeper is about rain forests, magic and ghosts amongst other things.
Take Dan Freedman. His football books are about relationships with girls, relationships with parents, etc.
Take Helena Pielichaty. Her football stories are about healthy eating, bullying, perceptions of foreigners and a hundred other things. As well as football.
Take Bali Rai, Michael Coleman, Alan Gibbons and a dozen others. We have our own obsessions that we pursue in our books just as much as we pursue football.
If you want to know what my biggest obsession is, it could well be dads. Being a dad. Being a son of dads.
I am a Dad writer as well as a football writer.
I had three dads.
I was adopted. My next mum and dad split up when I was four. Then, the dad who brought me up died when I was 21. That has made me think a lot about fatherhood. That all came to a head when I became a dad seven years ago. What sort of a dad should I be? Number one, two or three?
That was the time I started writing for children too.
My first book - Foul Play - is about a boy who solves football crimes. Spy and detective kids in books often have dead parents. It helps free them up to detect and spy. But I wanted Danny to have a dad he was really close to.
In Foul Play (and the other four books in the series) Danny reads crime books to his dad, who is blind. That's why Danny is so good at being a detective. He is empowered by the books he reads to his dad. They are close and Danny has to work within his dad's boundaries to solve the football crimes he solves.
In the Football Academy series I have thirteen boys, all with different dad relationships:
Boys United has a dad who backs his son all the way, but picks him up when he makes mistakes.
Striking Out has a dad that wants his son to give up football and concentrate on his schooling.
The Real Thing has a Polish boy and his dad, struggling with the bullying that the boy gets because of his accent and background.
Reading the Game is about a boy whose dad left when he was a baby and he's never seen him and he's not sure how to grow up.
Free Kick is about a boy whose dad wants him to be a chip off the old block, but the boy doesn't want that.
Captain Fantastic is about a boy who has a secret: his dad is in prison.
I am a football writer. But I am a dad writer too.
On Monday a lad came up to me at a school in Hull. He said his dad was in prison. He said he'd read Captain Fantastic. He said he liked it.
