Jonnie Wild’s interest in conservation was first stimulated by his own children's distress at learning about destruction of the rainforests. He set up the Yorkshire Rainforest project, which planted new forest trees in an Amazon area as big as Yorkshire, and now has similar projects all over the world. He pioneered many environmental projects in the tropics whilst leading his family business - the famous Betty's Tea Rooms and Yorkshire Tea and he now works with environmental scientists at the University of Leeds, supporting collaborative research and action in conserving forest habitats for the benefit of both animals and humans. Brita Granström's illustrations have won such top awards as the Smarties/Nestlé Silver Award, and the English Association Picture Book Award (no less than five times) and she has been twice shortlisted for the ALMA (Astrid Lindgren Memorial Award). Her most recent book, with her husband Mick Manning, is Books, Books, Books! Brita’s vivid memories of working as a volunteer for a flying doctor in Africa help to give authenticity as well as humour to her illustrations in The Mud Monster. Brita Granström lives in Berwick-upon-Tweed.
