Fern's Nanna has not been herself of late.

And when Mum remarks that all the joy seems to have gone out of her life, Fern decides to fetch the joy back. With her catching-kit at the ready, she goes to the park and finds joy in all sorts of unusual places. Whooooshh! But Fern soon realises that joy doesn't fit in a bag, or a box or a tin! How will she manage to bring some back to Nanna? Emotional, funny and uplifting, this beautiful picture book has a strong message about empathy and maintaining loving relationships with our grandparents.
