When a young girl visits her grandparents at the beach, she stays in a little house and walks along the shore gathering seashells—which were once little houses of their own. The girl wonders about the creatures who used to live in each shell, about the hidden treasures of the sea, and about the mysteries of the world. Kevin Henkes's text features striking imagery, depth of emotion, and a lovely multigenerational relationship, and it is perfectly complemented by Laura Dronzek's lush, saturated acrylic paintings.
