From the balcony, you can see the entire city. There are cinemas and ice cream shops ... and me! As Henry measures the distance between his new apartment and Grandpa's wooden house under the mango tree, Grandpa works out how close they really are. A moving story that celebrates the bond between a boy and his grandfather.
