Lunch Lady and the Video Game Villain (Lunch Lady Series #9) by Jarrett J. Krosoczka
The race is on for a new student council president, and the Breakfast Bunch is rallying for Hector! The competition is already heavy, but the race heats up when school security is at stake: student and staff high-tech gadgets are disappearing left and right. Whoever the culprit is, this is one stealthy thief—and the school is so busy with the election that he gets away with it every time. Luckily some of Lunch Lady's own culinary gadgets have eluded the crook, but will they be enough to catch this sticky-fingered bandit? And will Hector be able to pull off a victory?
