A startlingly original picture book about a little girl who creates a garden on a disused car park rooftop

Funni loves the old, disused car park, and spends a lot of time there flying her kite and playing her recorder. But something is missing. Definitely. So Funni decides to create a garden in the neglected space and after weeks of careful nurture, her garden in the sky takes shape. One day, a little boy, Zoo, spots the square of colour amongst the grey from an incoming flight, and decides to try to find it. And slowly, not only do Funni's flowers bloom, but a very special friendship blossoms too.
