Amy just got back from a trip to Earth with her parents, and she excitedly tells her friends all about the ghost she met in England.
Creasey's teenage-girl character really comes to life. The ghost's pitch that he'd help her spy on her friends is hilarious. When his rock won't fit in her bags, her decision to slice the blood stain off the rock is interesting, although it seems a little out of character for Amy.
From that point, it goes downhill. Amy's an unreliable narrator, but after that point we're unsure whether we're supposed to believe any of the story at all.
