Michael Wagner is the author of more than 70 books for children including the much loved, 20-book Maxx Rumble series (still in print after 15 years), the bestselling The Undys series, and the CBCA Notable picture books Why I Love Footy and Bear Make Den (co-written by his partner Jane Godwin). Heath McKenzie lives and works in Melbourne, and has illustrated many books for children (most recently the Do Not Open This Book series by Andy Lee and Tim Cahill's Tiny Timmy series). When he's not drawing, Heath is busy helping to raise a little family with his lovely wife, collecting unnecessary masses of toys, books and DVDs, indulging in a spot of Doctor Who and attempting ambitious culinary feats in the kitchen. He also enjoys possibly a bit too much tea.
