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.

Ada Grey studied illustration and later took a role in design. Moving back into illustration, Ada set about designing her own unique picture book style, characterised by an energetic palate, adorable, lively characters and a delicate use of texture.

Her books include Shhh! Don't Wake the Royal Baby, School for Dads, Poo in the Zoo and Hippobottymus. She has illustrated several books for Bloomsbury, Little Tiger, Egmont and Macmillan. Ada lives by the sea in Brighton with her daughter and ginger tom, Tiger.
