When Jimmy Liao was little he wanted to be several things: a painter, a magician, or a train driver. Eventually he became a painter who tries to create magic with pictures. (And who sometimes still dreams of being a train driver.) He is the author and illustrator of over thirty-two books that have been translated into nine languages worldwide. In a starred review, Publishers Weekly called his first book with Little, Brown, The Sound of Colors, "exuberant." He lives in Taipei, Taiwan with his wife and daughter.
