Oscar Grimstone is a normal kid—aside from his secret Curse. Whenever he touches something living, like a flower or his classroom goldfish, it always seems to die. But then Oscar discovers an even bigger secret: even though he is very much alive, he has the ability to transform into a ghost. Just when he thinks things can't get any stranger, two ghosts show up at his home in a skeleton carriage and he winds up joining them on a journey beyond the real world to a place where no human has ever set foot—the city of ghosts. There, Oscar will discover a place where people go when they die, before they board a ship to the Other Side. But will he find out who he really is?
