A celebration of reading and the huge phenomenon of dressing-up as your favourite character on World Book Day.

What will you wear on World Book Day?
Anna can't decide what to dress up as, but her dad knows just what to do to help ... He takes Anna to a bookshop where a friendly bookseller helps her to pick out the perfect book for her. Now she knows exactly what to dress up as!

But when she goes to school in her monster costume, no one knows what character Anna is supposed to be and she wishes she could share her favourite book with her classmates.

Can Anna find someone to share her favourite story with and discover just how much magic is hiding inside a book?

This magical rhyming picture book is the perfect story for sharing around World Book Day celebrations or for sharing the joy of reading all year round. Perfect for children aged 3 years and up, this is a fantastic celebration of stories, teachers, librarians and libraries, booksellers and the magic of discovering your favourite book and sharing it with others.
