Martha Mumford has loved children's books forever. Shhh! Don't Wake the Royal Baby is her first children's picture book and she is delighted to be working with Bloomsbury.

Martha loves baking, patchwork and has a mild obsession with interiors magazines (although she freely admits that the ideas she has found therein have yet to be translated to the interior of her own home!). Martha lives in Berkshire with her husband and young daughter.
