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. Nikki Dyson is the bestselling illustrator of Oscar the Hungry Unicorn, Oscar the Hungry Unicorn Eats Christmas and You're Called What?! Her other books include Dinosaurs Don't Have Bedtimes, Zippo the Super Hippo and Mack and the Missing Cheese. She lives in Northamptonshire.
