In this spooky-fun mystery, thirteen-year-old psychic Alex and his paranormal investigator friends face their biggest challenge yet: the hospital haunting. The friends are convinced that this surge of ghostly activity is far more devious than the “experts” suspect—and that only the ancient magic of an elusive swamp witch can put the ghosts to rest. Finding the witch means braving the Louisiana swamps full of gators and snakes, but if Alex and his team fail, New Orleans could become a realm of the dead. Book 4 in the paranormal mystery Ghost Hunters series is perfect for fans of Lockwood & Co. and Stranger Things.
