When Sebastian, a gifted violinist, is declared a prodigy, the whole Forum family follows him around the globe as he plays to enthralled audiences.
At first, it’s an exciting adventure for them all, but as the months turn into years, the children long for their sprawling, messy home, Apple Bough. And for Wag, the friendliest dog you could ever meet. While the Forum parents see their children as ‘world citizens’ on tour, Myra, Sebastian, Wolfie and Ettie are more homesick by the day. So Myra makes a plan – ‘Operation Home’ – and the children are determined to see it succeed.
