Off the Shelf

  • "Marty Moose is a chapter book for younger readers, that’s lively, exciting and adorably absurd. Think Brambly Hedge by way of The Twits!"

  • “On meeting Powell you can really tell the amount of passion she has for her stories and illustrations and the children at the event did too! The story itself is all about friendship, trust and bravery and I absolutely loved it!”

  • “Claire has such amazing energy, and interacted with the audience with humour and confidence. She expertly measured and adapted to the engagement of the young audience, and encouraged both group and individual artistic activities with ease… but most importantly, she connected with young readers over their natural urge to create artistically, and left them full of smiles and a sense of accomplishment.”
