We are her world and her universe and her space and her sky and her galaxy and her cosmos too. Frank is ten. He likes cottage pie and football and cracking codes. Max is five.

Sometimes Frank wishes Mum could still do huge paintings of stars and asteroids like she used to, but since Max was born she just doesn’t have time. When tragedy hits Frank and Max’s lives like a comet, what will it take for Frank to piece together a universe in which he and Max aren’t light years apart?
