When did you first decide that you wanted to become an author?
I always liked writing stories, even when I was five or six, but I never for once dreamed that it might become a career. I suppose the first time I thought about it was when I was a student and I tried to get poetry published but it only became a serious ambition when I was a schoolteacher in my thirties.
How did you celebrate when your first book was published?
I didn't really! I am from a Methodist chapel background and it is frowned upon to get over-excited or too proud of yourself. I did finally tell my wife what I was up to though (big of me!).
How do you decide what to write about?
Most of the time I just go with my own obsessions. I either write about the things I liked when I was a kid or else I pick up on something I have read, seen on the movies or the TV, something I have overheard in a conversation.
My Hell's Underground series came about because my publishers thought I could be much more ambitious about a horror story I had given them. They suggested a time slip tale over several books and I said, yes please, being a big Doctor Who fan. So that was basically a 'kick up the bottom' stimulus.
How long did it take you to write your last book?
It was about six months from beginning to end. There were a couple of weeks planning, a few months writing and a month redrafting.
What are you working on at the moment?
I am two hundred pages into the fourth book of the Hell's Underground series. It is called Witch Breed.
What advice do you have for budding authors?
I can't think of anything very original. You need to read a lot. You need to practice. You need to show your work to people your trust and ignore people you don't. You have to be disciplined, hard-working and ready to take criticism - even if you disagree with it.
Who is your favourite author and what is your favourite book?
I love reading like most authors so I will have to indulge myself by mentioning a few people. My favourite novelists for adults are Tolstoy, Solzhenitsyn, Balzac, Dickens, Charlotte and Emily Bronte, Stephen King, Steinbeck and Harper Lee.
My favourite novels are To Kill A Mocking Bird, Jane Eyre, One Day in the Life of Ivan Denisovich and The Stand. My favourite teen novels are Stone Cold, Noughts and Crosses, The Machine Gunners, Rose Red Snow White and Tunes for Bears to Dance To.
My favourite writers for teenagers are Robert Swindells, Philip Pullman, Malorie Blackman, Robert Westall, Marcus Sedgwick, Beverley Naidoo and Robert Cormier. My favourite writer for younger people is Roald Dahl. My favourite poets are Shelley, Blake, Shakespeare, Patten, Henri, McGough, Rosen and Zephaniah.
Tell us something unusual about yourself.
I am a Manchester United fan who lives in Liverpool (I'm not a Scouser).
