Martin Jenkins is a conservation biologist and author of many groundbreaking non-fiction books. He worked for ten years for World Conservation Monitoring Centre, writing about a range of conservation issues, and since 1990 he has worked freelance for organisations such as WWF and a number of UN bodies concerned with conservation and the environment. Martin's jobs have varied greatly: "I've been an orchid-sleuth in Germany, a timber detective in Kenya and an investigator of the chameleon trade in Madagascar." Martin's children's books include Emperor's Egg, winner of the Times Junior Information Book of the Year Award. Martin lives in Cambridge. Jane McGuinness studied illustration at Maidstone for her BA before completing an MA in Children's Book Illustration at the Cambridge School of Art.

In 2016 Jane was awarded the Sebastian Walker Prize for Illustration. Her first picture book, Say Hi to Hedgehogs, was published in 2018. She lives in Birmingham.
