Author Terry Deary has a pretty good idea of why his Horrible Histories series is so popular.
"The problem with non-fiction books is they're written by experts who wouldn't know a child if it jumped up and bit them on the kneecap," he says.
"The reason Horrible Histories has been a success is I'm a fiction author. I published 50 fiction books before I turned to Horrible Histories."
