And really - it's next to nothing
Here's what I know ..
It was set in the UK. British author
Features a teenage girl called Minty, possibly short for Araminta. Think she has a brother.
Will be set in the 70s I should think as that's how old it is. Could just sneak into 1980 maybe
Author someone like Nina Bawden although I know it isn't her.
Err anyone?
