I’ve written a gazillion books (nearly), and lots of them are featured here*. The books nearest the top of the page are newer and will be easy to get hold of, either in bookshops or to order (from your local bookshop or online). And don’t forget about wonderful libraries in your area or in your school; you can grab my books there too!
* Lots, but not all! Some of my earliest were written under a pseudonym, fact fans!
