Finding himself alone on a desert island when everything and everyone he knows and loved has been washed away in a huge storm, Mau is the last surviving member of his nation. He's also completely alone - or so he thinks until he finds the ghost girl. This children's novel encompasses the themes of death and nationhood.
When a small boy turns up on Bob and Joan's doorstep unable to say much except 'I was a rat', the kindly couple adopt him. It seems strange but Bob reads about odder things every day in his newspaper. To them, the sunny little chap is Roger, and he's trying hard to adapt to human life.
