Gruffalo creator Julia Donaldson signs books at the Mitchell Library A gruffalo? What's a gruffalo? A gruffalo! Why, didn't you know? The Gruffalo, a rather unfortunate looking monster, has captured the hearts and imaginations of children across the globe. Its creator, Julia Donaldson, adapted the children's story from an old Chinese fable and it has since become an overwhelmingly popular book, now translated into over 40 languages. As part of Pop Up Book Week, the revered children's writer will be popping in to the Mitchell Library to do a book signing at 11am this morning. But who is this creature with terrible claws? And terrible teeth in his terrible jaws? He has knobbly knees, and turned-out toes, and a poisonous wart at the end of his nose. If you've been living underground for a few years (or don't know any children) and haven't heard much about Julia Donaldson, you can listen to an interview with her below. Heading along to the book signing? Let us know by tweeting @STVGlasgow.
