I gave this book an “R” rating for it’s humor.  (About practicing his trumpet, Griff says, “I hadn’t practiced since my underwear had Power Rangers on them.”)  Seventh-grader Griff Carver is the new boy at Rampart Middle School.  He has a little bit of big head because he’s a hallway patrol monitor, and takes it ever so seriously, much like Sargent Friday of Dragnet. (“Silence is one of the perks of hall duty.  Giving up study hall three days a week and school assembly on Fridays is a small price to pay for walking a beat.”)  One thing that makes Griff such a good hallway patrol monitor is that he’s extremely observant. (“He had dirty fingernails and the look of a kid who sharpens his pencil too long just to be annoying.”)  Humor is joined by a mystery Griff is ready to solve….Who is at the bottom of the counterfeit hallway passes?  Plenty of action, and even a little horror at the climax of the story will have readers thinking they’re reading a sitcom script.
