Inside a hidden box, a group of children discover a stash of seaside mementoes from a time long gone. Among the items there is a torn map.
They follow the trail shown on the map and soon find themselves deep in the heart of an old seaside pier – and back in the past.
The illustrations, in watercolour, gouache and ink, cleverly show a town changing over decades, a little like we see in Jeannie Baker’s Window and Belonging.
