Zoë Tucker is passionate about picture books and spends (almost) every day in the world of children's publishing. Working as an art director and designer, she has the opportunity to work with authors, artists, and publishers from all over the world. Zoë lives and works on the south coast of England, with her husband, Adam, and her cat, Murray, and she uses a computer (almost) every day! She is the author of many children's books including: Greta and the Giants (Frances Lincoln Children's Books) and Ada and the Number-Crunching Machine (NorthSouth Books). Rachel Katstaller is originally from tiny tropical El Salvador, where she studied Strategic Design. After a period in Montréal and New York, where she attended the Summer Residency in Illustration at the School of Visual Arts in the summer of 2014, Rachel relocated to the Alps together with her cat Hemingway. Rachel now works for several international publishing houses concentrating on children's books and editorial illustration. She also has her own apparel brand, Las Furias.
