S.F. Henson: Hello. My name is S. F. Henson. Why initials? Well, my first name is Sarah, and with my last name Henson, I was worried it sounded too close to the hugely talented YA author, Sarah Dessen, so it was initials. And I love even numbers, so two letters it was. The F is for my maiden name, Frederick, and my last name is easy to remember, because it's Henson, like the lovable Jim Henson who created the Muppets.
