Mystery Bottle by Kristen Balouch:
A boy in Brooklyn receives a package from Iran. When he opens up the mysterious bottle that lies within, a great wind transports him over the oceans and mountains, straight into the arms of his grandfather. Despite being separated by politics and geography, the boy and his Baba Bazorg can share an extraordinary gift, the bond of their love.
Nearly every page of this delightfully illustrated children's picture book uses maps in the background; from Brooklyn, to the Atlantic Ocean, to Iran.
