Ursula Moray Williams wrote and illustrated over 70 children's books in her lifetime. Born in 1911, she was one of identical twins, both of whom started to write and illustrate their own books at a young age. After spending time in France, Ursula's first book Jean Pierre was published when she was just twenty. Set in the Haute-Savoie region which she knew so well, it followed the adventures of a small boy and his pet goat. Moray Williams wrote her most famous story, The Adventures of the Little Wooden Horse, in 1938, in which a little toy horse is separated from his toymaker `uncle' and must endure many dangerous adventures before finally finding a happy ending. A few years later in, 1942, she went on to write Gobbolino, the Witch's Cat, which soon became a firm favourite with children. Her books have been illustrated by Edward Ardizzone and Shirley Hughes, among others. A new edition of Gobbolino, the Witch's Cat was published in February 2012 on the 70th anniversary of its publication, and Moray Williams' classic tale of courage and hope, The Adventures of the Little Wooden Horse, was reissued in October 2011. Catherine Rayner studied illustration at Edinburgh College of Art. She fell in love with the city and still lives there with her family and a small menagerie of creatures including Shannon the horse, Ena the cat and a goldfish called Richard, all of whom inspire her artwork. In 2008 Catherine was selected as one of the Ten Best New Illustrators for Booktrust's Big Picture Campaign. She has been short-listed for the prestigious Kate Greenaway Medal four times, and won in 2009 for Harris Finds His Feet. In addition to illustrating for other authors such as Michael Bond, Holly Webb and Michael Morpurgo, she has also written her own picture books, including Ernest, Solomon Crocodile, Solomon and Mortimer and Smelly Louie, which won the Peter's Book of the Year award in 2015.
