Laugh out loud with Captain Underpants, from Dav Pilkey,

the creator of Dog Man! 

The Radioactive Robo-Boxers are back

in the tenth full colour book in this #1 New York Times

bestselling series.

When we last saw our heroes, George and Harold, they had been

turned into evil zombie nerds doomed to roam a devastated,

postapocalyptic planet for all eternity. But why, you

might ask, didn't the amazing Captain Underpants save the boys from

this frightening fate? Because Tippy Tinkletrousers and

his time-traveling hijinks prevented George and Harold

from creating Captain Underpants in the first place! Now, having

changed the course of human history forever, they'll

have to figure out a way to change it back!
