"Gary Yorkshire is finally getting into the swing of this whole superhero thing - saving the world from terrible villains, masterfully concealing his identity with a very small mask. But what happens when Batpig is called to battle time itself in a maths class that just won't end? Or when the city is attacked by something completely (and literally) out of this world? It's not easy being a super-swine, but with the help of his best friends Brook the bat and Carl the fish, there's no hamburglar they can't catch."--Publisher.
