An exciting intergalactic adventure from shining star Oliver Jeffers, creator of Lost and Found. One day a boy finds an aeroplane in his cupboard.

Up, up, up and away he flies, high into the sky. Whizzing past clouds, stars and planets until suddenly, he runs out of petrol! Miles from earth, the boy crashes into the moon and waits.

Just as he is beginning to get cold and lonely, a friendly martian appears from the darkness, also with a broken aircraft. Together they come up with a super plan to float the boy back down to earth to collect his toolbox. Can the boy find his way back home safely and will he ever make it back up to the moon to rescue his friend?
