For fans of Because of Mr. Terupt, Mr. Terupt Falls Again, and Escape from Mr. Lemoncello's Library, this funny, suspenseful adventure is about two very different twelve-year-old boys who must save the world from demons while dealing with parents, school, bullies, and girls.
 
Walter Prairie knows how to deal with bullies. He just has to beat them to the punch. But he doesn't see the biggest hit of his life coming when he is struck dead by a bolt of lightning. Before Walter even knows what's happened, he is sent to a Categorizing office, fast-tracked through the Afterlife Academy, and assigned as a Guardian Agent to protect a High-Level Target.
Walter's HLT, Charlie Dewdle, isn't exactly the most popular kid in school. He's what you might call paranormally obsessed. When Charlie finds an ancient book with spells that can be used to open the Gateway for demons to wreak havoc on earth, it's up to him and Walter to fight an eclectic horde of enemies and protect humankind at all costs.
     But saving the world isn't so easy. Especially when your protector doesn't know the first thing about the Underworld, bullies like Mo Horvath are trying to hunt you down, pretty and popular Melissa Bittner is suddenly talking to you, and your parents think you're going crazy.
