But please note that Mary receives such a volume of e-mails that she can answer them only once a week, and often can't quite manage to do it even that regularly so do not be surprised if you do not get a reply by return. She will not answer if your question is answered in the FAQs section, so please check there first, especially if your question is about further Stravaganza titles, book covers or a film.
You can also write to her c/o
Bloomsbury Children's Books
50 Bedford Square
If your question refers to the publication dates of Stravaganza novels in specific countries, please direct it to the publisher, as Mary does not have this information.
