Few Australian children grow up without encountering the books of Emily Rodda (whose real name is Jennifer Rowe).

Her Deltora Quest series has sold more than 15 million copies around the globe, with subsequent spin-offs including the Star of Deltora, The Three Doors and Rowan of Rin series.

Or perhaps you know her from her other series – including Fairy Realm, Teen Power Inc, or the Rondo or Three Doors trilogy – or her standalone books, including Pigs Might Fly, The Julia Tapes, His Name Was Walter, The Glimme and Finders Keepers.

She has written books for older readers under her own name, including the Verity Birdwood mysteries; and for younger readers, there’s the Monty’s Island books – the latest of which, Scary Mary and the Stripe Spell, was released in March.

Emily Rodda has agreed to be part of Guardian Australia’s regular series, Ask a Children’s Author, in which young readers (and older fans) get a chance to interview the writers they love, asking questions about the books, their characters – about anything at all, really.

You can either post the question in the comments below or film it being asked – and email the video to australia.culture@theguardian.com with the subject heading “Emily Rodda”. Please also include the question-asker’s first name, age and city.

The question might make it into the video we publish with all her answers – so long as you send it before Monday 24 August.
