At the same time, I think books create a sort of network in the reader's mind, with one book reinforcing another. Some books form relationships. Other books stand in opposition. No two writers or readers have the same pattern of interaction.

The novels take longer to write than the picture book texts, and they do take a different sort of concentration. However, a very short, simple story that works well is just as exciting to me as any longer and more complex book.

New Zealand is the only country I know well enough to write about. It can sometimes lead to complications.

Being a librarian certainly helped me with my writing because it made me even more of a reader, and I was always an enthusiastic reader. Writing and reading seem to me to be different aspects of a single imaginative act.

There are certainly times when my own everyday life seems to retreat so the life of the story can take me over. That is why a writer often needs space and time, so that he or she can abandon ordinary life and "live" with the characters.

When I was a child I had a best friend who lived across the road from me. When her mother died unexpectedly it was like losing a member of my own family. I think I am still affected by the memory of that loss.

I am really chained to my computer these days so I work in my bedroom, which is a room I have worked in for years and years. It is just as much an office as a bedroom, and during the day, my bed is rather like an extension of my desk.
