He lives with his family in the Midlands, and spends his spare minutes sleeping. Kate Nolan (Author) Kate grew up in the Cotswolds and now lives in the West Midlands, where she worked as a primary school teacher before joining Usborne in 2019. Since then, she has worked on books on all sorts of topics, from airports and trucks to unicorns and butterflies. Sam Smith (Author) Sam grew up in Buckinghamshire, falling off various bicycles before reading books and making up his own stories about more competent heroes. After studying English at Cambridge University, he joined Usborne in 2013, and now writes titles ranging from fold-out solar systems to maze books full of swashbuckling pirates. Sometimes, Sam cycles to work.
