Most people don't realise that an entire Ghost World exists alongside their own. They are not aware that they walk with ghosts every day. Tom Golden is the only one who knows, the only one who can see them. But when his friends start becoming visible to everyone else, he realises something somewhere has gone very wrong. Can he put it right before the two worlds collide?
The Ghost World sits right on top of the Real World, overlapping it at the edges. This is the way it has been for hundreds of years. But not until now has there been a story like that of Grey Arthur, an ordinary ghost, with no particular talent for haunting.
In many ways the Ghost World is like the Real World and, in many ways, Ghosts are just like Humans, except they are never born and they never die. One day they appear and then one day they're gone. But recently more Ghosts than usual have been disappearing, just vanishing into even thinner air. So many, so quickly, that it can only mean one thing.
