Oh No! Not Again! (Or How I Built a Time Machine to Save History)

Illustrated by Dan Santat

It’s a terrible thing when you mess up on your history test. It’s even worse when you mess up all of human history.

“Wonderfully ridiculous in premise and execution.”

Kirkus Reviews

, Starred Review

“Barnett’s deadpan prose and Santat’s page-popping art hilariously reveal what happens when you mess with history.”

Publishers Weekly

, Starred Review

“Whether they are shoving paintbrushes up their noses, spray-painting their faces, or stabbing each other with pencils, readers will find these Cave Stooges irresistible.”
