Enter the Ghost Finders, ready to confront the enraged poltergeist and battle for the students' very souls.
It's all in a day's work for the Carnacki Institute operatives - except this day is going to get very nasty indeed. What they're about to discover is that another entity had also breached the veil between worlds and crossed the threshold into ours . . . and they soon realise that it's not just four lives at stake, but all lives - humanity itself is being threatened with annihilation.
Voices From Beyond is the fifth book in New York Times bestselling author Simon R. Green's Ghost Finders series.
