From award-winning Portuguese duo, Isabel Minhos Martins and Madalena Matoso, comes another truly inventive picture book that takes readers on a sensory adventure in the pursuit of friendship. Rendered in Matoso's distinctive, eye-catching style,What's That Noise? invites young children to investigate who exactly is calling them from inside the book. Readers will delight in following the clues by 'tip-toeing' with their fingers through an empty forest, braving a terrible storm of their own making, holding their ear up to the book to discern where to turn next and creating a shelter for their new friend when danger looms. A story that can only be told using fingers, eyes, ears and noses, What's That Noise? engages readers on all levels, and shows that to build a friendship takes time, patience and an adventurous spirit.
