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.
Sarah grew up in the West Midlands, where she spent her days reading, running and making her own magazines. She studied English and Film at university, and in her spare time, you'll find her knitting in a coffee shop or defending shots on the netball court.
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. Incurably curious, she loves the challenge of writing about anything from aardvarks to zombies.
