It is exciting times for Zsa-Zsa and William when they set off with their mummy, and their fluffy dog Merlin, for a weekend sleep over. In the rush to leave, mummy leaves a tray of lavender plants on the rocking chair After a wonderful time staying with mummy's friend Coco and her family, they return home. But when Mummy moves the tray to sit down she is alarmed to discover a stowaway slug. It is going to be up to William to prove that he is not afraid of slugs and be the hero of the hour.
This is a beautifully illustrated story of how a young boy can overcome his fears to protect nature and save his family from the awkward situation they find themselves in. It shows that small creatures can be just as scared of humans as we are of them. A story to show the right way that we should deal with nature and little animals around us.
