Matthew Morgan and David Sinden co-developed and wrote the YUCK stories. They're lifelong friends who met at a primary school sports day and grew up in Kent. Matt and Dave both worked in children's publishing before turning to fulltime writing. They also write AN AWFULLY BEASTLY BUSINESS series with their friend Guy MacDonald. Nigel is an experienced book designer who has worked for various trade publishing houses. Simon and Schuster loved his work so much they chose him to illustrate the highly successful YUCK series. Nigel is a keen walker and would like to spend half the year living on top of the Andes. His other great loves are Grantham Town Football Club and any kind of travel.
