United Middle School - Paperback

Strange things are happening at United Middle School, and when the fire alarm goes off without any fire, it's just the beginning. Jake, Emily, Amy, and Max-four curious friends and sharp investigators-team up to crack the mysteries that leave everyone else stumped.

From disappearing lunches to a prank war that spirals out of control, and even a teacher who mysteriously turns into a kid, these young detectives are ready to face whatever oddities come their way. But when they uncover secret rooms, vanishing artwork, and a traveling notebook with clues of its own, they realize some mysteries are bigger than they imagined.

With their wits, teamwork, and a little luck, can they solve all the puzzles hiding in the hallways of United Middle? One thing's for sure-there's no such thing as an ordinary day when the young investigators are on the case!
