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.

Maddie Frost creates her illustrations by making handmade textured and patterned swatches with materials like watercolour paint, crayon, pencils, and even kitchen spices! She scans the swatches into Photoshop and digitally cuts the shapes she needs to make something.

Her final images can consist of anywhere from fifty to five hundred pieces that are all layered together. Maddie lives in Arlington, Massachusetts, with her husband.
