Gillian Cross lives with her family in Warwickshire.
I write because I have always been curious about what it would feel like to be someone else, in a different situation. Fiction is a wonderful way of exploring that. As a child, I did it by dressing up and imagining adventures for myself. Then I discovered that writing the adventures down made them more vivid and absorbing, because I had to sharpen up my imaginary world if I wanted other people to visualise it. Sharpening up the imaginary world helped me to understand the real one better and sparked off more questions. The older I get, the more my curiosity grows, and every book I write is a new exploration.
