The chalk was almost gone.
A girl and her father spend a long summer afternoon drawing a dragon across the whole driveway. Then he opens one enormous eye.
Gemethy doesn't know what he is. The girl does. What follows is one afternoon, and then the weather, and then a promise that has to last a great many summers.
Every illustration in this book is a photograph of real chalk on real pavement - and there is no picture of Gemethy anywhere in it. That is on purpose. Anyone can draw a dragon; only you can draw yours.
For children still being read to, and for the grown-ups doing the reading.
