My Life as a Haunted Hamburger, Hold the Pickles [EPUB ebook] 

Everybody says the old house at the edge of town is haunted. But Wally has some major doubts. Unfortunately, in exposing the hoax he undergoes some of the craziest catastrophes and mass mayhem of his life. To name just a few, Wally experiences: falling into mirrors that others claim show the future; shorting the sheets on so-called ghosts; and supposedly being turned into a talking hamburger. All this as our young hero learns what God really says about sorcery, ghosts, and the supernatural.
