I came into children's books originally as Editorial Director of a nationwide children's book club, though I had written and directed a children's play while a student at Sussex University, which was performed at the Edinburgh Fringe. I wrote my first two children's picture books in 1984 and was lucky enough that Anthony Browne wanted to illustrate the second - Knock Knock Who's There? It was published in 1985, is still going strong today and is one of my most successful.
Shhh! was published in 1991 and has known great success in France/Belgium in particular (close on 300,000 copies sold). It's success in the UK - it won the Children's Book Award - was hampered by the liquidation of its original publisher.
I became a full-time author in 1995 and now have some 150+ titles published, the most recent being L'Histoire du Soir in France, Belgium and Italy.
Feather Wars, published in 2003, was my first sortie into young fiction and was followed by the very successful Spilled Water, which has been published in some ten different languages and is very popular in schools as a class reader. It won the Nestle Smarties Gold Award (and I wound up being a 'Pointless' answer on the back of it!) Broken Glass came next and was a Sunday Times Book of the Week.
I'm currently working on picture books again and have plans to illustrate one of my own in the not too distant future - watch this space!
