Hellish Book Four: Vizibir (Paperback) (ISBN-13: 9798990869608)

Everyone has an imaginary play friend as a child at one time or another, someone they can play with, someone to talk to when they're lonely. But when Jeremy's invisible friend manifests itself into something real, very bad things start to happen. Before long an unimaginable evil is set loose on the world, and Jeremy's own death may be the only way to stop it.
