The Secret Plan of 4b

                            Something isn’t right at Regelberg Elementary School. Overnight, strange new rules appear everywhere—rules that weren’t there yesterday. Laugh only at 10:12 a.m.? Spontaneous idea detected → fill out a form? Deviation from the plan = mandatory paperwork?

Milo discovers a secret note with a suspicious stamp. Fina knows immediately: this isn’t a normal note. It’s… official. And Turbo? He accidentally stumbles into a mystery that’s supposed to make the entire school “perfect.”

But perfect is dangerously boring.

When the three uncover the secret plan of Class 4b, one thing is clear: PROJECT PLAN-PACKAGE is already running—and the plan is writing itself!

Now Class 4b needs a counterplan… one so wildly creative that no stamp in the world can stop it.

A funny school adventure for ages 8 and up—with short chapters, big laughs, and tons of chaos, teamwork, and fun!
