Lucy Rowland grew up in Cheltenham but currently lives in London where she works as a Children's Speech and Language Therapist. With a real passion for language and lots of experience working with young children, Lucy was thrilled when she finally made the leap into picture book writing.

When she's not daydreaming about story ideas, reading A. A. Milne or thinking up fun new rhymes, Lucy enjoys backpacking, baking and long walks on the beach. She is rather scared of spiders (and spider-related tricks!) but has now (bravely) done the highest bungee jump in the world!

Mike Byrne grew up on the Wirral near Liverpool before moving to Wales to study Illustration at Glyndwr University. He began his career as a designer for a greetings card company and then became a studio manager for a licensed stationery designer before leaving to fulfil his dream of illustrating children's books.

Mike now lives in Surrey with his wife, cat and two sons where he spends his days doodling and illustrating children's books fuelled only by tea and biscuits. Mike illustrated the Jack's Mega Machines series for Simon & Schuster. The Return of Sproutzilla is his fourth title with Macmillan
