The fourth and final installment of the New York Times bestselling series!




It's Miles and Niles's final year at Yawnee Valley Science and Letters
Academy, and the Terrible Two have one goal: an epic prank. Something
that will leave a lasting legacy at their school. Which should be
easy-peasy for these experts. But their smooth sailing gets downright
bumpy when they find out that the new superintendent is none other than
Bertrand Barkin, their principal's father . . . and their sworn enemy.
Now that former Principal Barkin is Acting Superintendent Barkin, he has
a first order of business: his long-promised revenge on the Terrible
Two.



This rollicking finale to the bestselling series by Mac Barnett and Jory
John will settle once and for all who-between quick wits and powerful
fists-will have the last laugh.
