When Jessica sits down next to Francis on a bench one break time, he's surprised to learn that she isn't actually alive-she's a ghost. And she's surprised too, because Francis is the first person who has ever been able to see her. Before long, Francis and Jessica are best friends, enjoying life more than they have in a long time. When they meet two more friends who also can see Jessica, the question arises: what is it that the children have in common? And is it connected to the existence of Jessica's ghost?The answer, when it emerges, is both surprising and moving-and leads to a dramatic conclusion that none of them could have foreseen.
