Claire is a bestselling children’s book illustrator working in London, UK. She started out designing for big-hitting television brands, before an impromptu visit to a children’s book exhibition led her down the path of illustration. Self-taught, Claire got her first book deal in 2015 and has never looked back.

A hugely versatile artist, Claire has a talent for creating characters that are brimming with emotion and personality. Her sense of humor often infuses her work, which ranges from delightfully silly tales of octopi searching for pants (Octopants) to festive rhyming romps about Santa preparing for Christmas (The Night Before, The Night Before Christmas). Her strong eye for detail and composition is demonstrated beautifully in the Heels of History series, where historical details are woven into her heartwarming, emotive scenes.

When Claire isn’t working she enjoys drawing in her sketchbook, taking long walks, reading and people watching. She’s also rather partial to an occasional cup of English tea. Find out more about Claire at
