In exchange they will reward her with the chance to make Melina real in the human world. However, the kids can’t leave Moorhouse until the contest is over.One of the other kids claims that the monsters can’t be trusted. He says that there was another contestant who disappeared before Vita arrived. But no one else can remember the missing boy at all.Time is running out for Vita to unravel the mysteries of Moorhouse—otherwise she could be next.
