Before she wrote books, Marianne was an actress. Not the famous sort, though. After graduating from Cambridge University she appeared in a few TV shows and did a bit of comedy on Radio 4. She has been in a film, in which she managed to forget both her lines. Since then, Marianne has written for The Story of Tracy Beaker, introduced America's Next Top Model and been the voice of a yogurt. She lives in London, and spends her spare time eating cheese and hassling other people's dogs.
Ali Pye has illustrated more than 30 books, including several picture books and the Harry Stevenson young fiction series.
Ali studied fashion at Central St Martin's before taking an MA illustration at Kingston University. She lives in London with her family, two guinea pigs and the world's greediest spaniel.
