J W Ocker: Welcome to the Ghost Show, Gebunden

Blurb

The Ghost Show is coming . . . are you ready? Three friends must face their deepest fears in this spine-tingling horror novel by USA Today bestselling author J. W. Ocker that's perfect for fans of R. L. Stine and Mary Downing Hahn.
When mysterious ads for the Ghost Show appear around town, nobody can tell what it is. A band? A movie? A game? But that magic word—ghost—excites Hazel Gold, or Zel to her friends. As founder of her school’s Creepy Club (three members strong!), she’s always looking for paranormal activity.
Turns out the Ghost Show is a black, five-story skull that appears on the edge of town as a supernatural attraction. Stepping inside, the Creepy Club is greeted by the eccentric Amadeus Everest Mancer, a self-proclaimed ghost catcher who guides them through an aquarium full of vaporous floaty things—sheets that cover gobs of dripping red goo.
Then Mancer offers Zel what she’s always wanted: the chance to see a real ghost. But it turns out to be more than she bargained for. To stop him, the Creepy Club must fight a massive ghost infestation and free the trapped souls within, culminating in chilling battle that blurs the line between reality and the supernatural.
