"Griff Carver: Hallway Patrol," by Jim Krieg (Penguin Young Readers, 272 pp., ages 9-11)
If there's such a thing as a good-natured police procedural for young readers, "Griff Carver: Hallway Patrol" is it. A savvy hallway patrol veteran, Griff Carver's skills are tested when he moves to a new school and begins to suspect the existence of a forged hall-pass ring – involving, of course, one of the coolest kids in school. Will Carver get his man – or will he get his school lunch tray handed to him on top of his head? Prepare for plenty of action and plenty of laughs.
