There are four of us, and we were all born in different cities because my dad worked all around the place. We settled in Birmingham, so I spent most of my time growing up there. We were all given very Welsh names - Geraint, Owen, Rhiannon and Gwilym. My mum's called Cainwen, and my dad is somewhat disappointingly called Tom.

When I get a job, I buy one really nice thing to have something to show for it.

More than fantasy or even science fiction, Ray Bradbury wrote horror, and like so many great horror writers he was himself utterly without fear, of anything. He wasn't afraid of looking uncool - he wasn't scared to openly love innocence, or to be optimistic, or to write sentimentally when he felt that way.
