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.
Kirsteen Robson (Author)
Kirsteen Robson joined Usborne in 1997 with a background in music, education, and Christian publishing. She has written and edited over 300 Usborne titles, from dictionaries and encyclopedias to activity books with flaps, stickers and sounds. She loves the challenge of writing about anything from aardvarks to zombies.
