In Belladonna Johnson's world, talking to ghosts seems perfectly normal.

She even lives with two - her recently deceased parents, who are still very much involved with their daughter's life.

But then the ghosts start disappearing. Before her father slips away, he warns her that the doors are closing, but Belladonna doesn't understand what he means.

She realises, though, that evil forces are at work, and if she can't stop them, she might lose everything.

With her friend Steve, she sets off on a trip that will test them to their limits, as they discover the dark secrets that lurk on the Other Side . . .
