The first book in the Liberty Falls Elementary series! Class 507 is so terrible that when a science experiment goes disastrously wrong, their teacher quits in the middle of the lesson. But through a mix-up, the school office never finds out. Can these fifth graders keep it a secret? Or will the greatest school year ever turn into the worst disaster in school history?

“Aimed equally at boys and girls, this engaging comedy offers some life lessons with a giggle.”

– Kirkus Reviews

“Told from the alternating perspectives of five classmates, this story of students joining together to learn lessons not always taught in classrooms will be a good fit for readers ready to graduate from the Captain Underpants series.”
