Rosa and her family live in a house in the country where an apple tree grows. With short stanzas, interspersed with occasional vocabulary in Spanish, we journey through the year and witness the tree as it changes and develops fruit. We discover what makes the tree grow strong and how the flowers are pollinated. Eventually the apples are fully grown and ready to be picked. On a warm late summer afternoon we join Rosa and her family for a celebratory picnic where a specially-made apple pie takes center stage.
