Tim Button started writing as a kid when he and his grandmother would write letters in poem form and send them back and forth. Today he spends his days advising businesses about technology. He loves sports of all kinds and has coached almost every kid's sport except for Lacrosse. He is known for joking around--often using different voices, which is not surprising because he's also worked as a voice-over artist. Tim lives in Moorestown, NJ, with his wife, three no-longer-wiggly children, and two dogs.

Ana Martín Larrañaga was born in San Sebastian, Spain, and grew up in the countryside of Castilla, in a huge family, surrounded by cousins and animals. At school, she drew little stories on every possible piece of paper. In Salamanca, where she studied Fine Arts, teachers told her to draw very big things. When she finished her studies, she returned to her small drawings and became an award-winning illustrator. Ana lives in Germany with her husband, three sons, and one cat. She likes swimming in the sea in the summer and knitting in winter.
