They best way to contact us is probably through the contact form on this website but do also feel free to try @perditact on Twitter or contact Jade, our publicist at S&S.
We aim to adhere to the Society of Authors' guidelines on charging for school visits (£150 for a single session, £300 for a half day) but we are aware of the funding challenges facing many schools so please do always get in touch to talk this through with us. We would only charge travel expenses outside London.
We would love to sell and sign some books and we know that personal signed copies can be a big boost to reading - if you don't have a supplier you use regularly please do ask us and we can help putting you in contact with a local bookseller, a wholesaler or our publisher. And of course it would be lovely to have support in the form of letters home to parents that might fund the book purchases!
