I first met Steven when he played the role of Horrid Henry in the original stage production (and you can read ‘How We Met’). We have lots in common and he is one of my best friends. He’s now become a very successful children’s writer and has recently published The Diary of Dennis the Menace. We’re having lots of fun doing some events together this year to see who is really king of the bad boys! You can find out more about Steven’s brilliant books and other events on his website. And you can also listen to Steven reading an extract on the Puffin blog.
