I have a wonderful agent called Sophie Hicks, and she is at the Ed Victor Literary Agency in London. She can be contacted through their website at www.edvictor.com
My publishers for The Butterfly Heart as well as for my next book are Walker Books, also in London. They have for over thirty years been producing aastonishing books for children and young adults and I am delighted they chose to publish two of mine.
