Kath Grimshaw is a writer, illustrator and children's book designer. She has Obsessive Compulsive Disorder and, as a child, she struggled to understand why she felt the way she did, which inspired her to write Frankie's Foibles.

She now freelances from her hometown of Totnes, Devon, where she lives with her husband, two boys and three cats.
