It turns out the new teacher, Mr. Cooper, is even weirder than Mr. Granite! One day he's Rat Man and he teaches about rodents. The next day he's Lava Man and he teaches about volcanoes. But what happens when the school is threatened by a supervillain and a real superhero is needed? Will Mr. Cooper protect the school from evil, or just embarrass it to death?

Perfect for reluctant readers and word lovers alike, Dan Gutman's hugely popular My Weird School series has something for everyone. Don't miss any of the hilarious adventures of A.J. and the gang--from Weird, to Weirder, to Weirder-est!
