Summer is here and Ana and HENRY THE STEINWAY are about to embark on a great adventure! Ana's father, the famous concert pianist, is taking them an exciting world tour, to premier new music written by his friend and composer Grace. Ana, along with her best friend, Lily, travel to Buenos Aires, Paris, London, Tokyo, Hamburg and Los Angeles. But first, HENRY must be hoisted out the apartment window! Then he's trucked to the airport and into the jumbo jet that will fly him across the Atlantic! During their world tour, Ana and Lily meet new friends from many different countries and participate in a world children's concert in London's Royal Albert Hall. By sending postcards to their friends back home, Ana and Lily share their most exciting summer ever!
