Dean Hale is the New York Times bestselling coauthor of more than 20 books for young readers, including the Eisner Award nominee Rapunzel's Revenge, the popular early chapter book series The Princess in Black, two graphic novels about young Wonder Woman, and two novels about the Unbeatable Squirrel Girl. It has been said that if you look in the mirror and say Hale's name three times, he will appear and give you a piggyback ride. This is mostly untrue. Douglas Holgate is the illustrator of the #1 New York Times bestselling series The Last Kids on Earth from Penguin Kids, now an Emmy Award-winning Netflix animated series, and the cocreator and illustrator of the graphic novel Clem Hetherington and the Ironwood Race (Scholastic Graphix). For the last 20 years, he has made books and comics for publishers around the world from his garage in Victoria, Australia.
