Lubna's best friend is a pebble. She found it on the beach when they arrived in the night, then she fell asleep in Daddy's salty arms. Lubna tells Pebble everything. About home. About her brothers. About the war. Pebble always listens to her stories and smiles when she feels afraid. But when a lost little boy arrives in the World of Tents, Lubna understands that he needs Pebble even more than she does.
