George and Ghost by Catriona Hoy and illustrated by Cassia Thomas
Synopsis: George and his friend are inseparable, but George isn’t sure he believes in Ghost any more. He asks Ghost to prove he is real by weighing himself, having his photo taken and showing he takes up space. But the scales don’t move, Ghost can’t be seen in the picture and the water in the bucket doesn’t spill when Ghost stands in it. Ghost can’t be real. Or can he?
