Celebrate twenty years of Sharing a Shell with this special, shiny anniversary edition with never-before-seen bonus material from the fantastic partnership of Julia Donaldson and Lydia Monks - the bestselling team behind the What the Ladybird Heard adventures.

When Crab finds a new shell, he doesn't want to share it with anyone - especially not a blobby purple anemone and a tickly bristleworm. But life in the rock pool proves tougher than Crab thinks and he soon finds he needs his new housemates.

Sharing a Shell is a charming underwater tale of friendship and fun. With brilliant rhythmic verse and bright distinctive illustrations, this is a firm favourite with children and parents alike.
