So your brother's a world-famous violinist? That's amazing! Or is it?

The Forums are a musical family, and one child, Sebastian, shines out as a prodigy. He is a brilliant violinist and when his talent is recognised, he is wanted the world over. Myra, Wolfgang (named after Mozart) and Ettie thought it was wonderful at first, but after four years of touring the world with their brilliant brother they've changed their minds. Now, what they long for, is a home of their own, not a hotel in Vienna or Venice or Moscow.

But to their mother and father, a life of travel is exciting - all any child could want. How can the children make the grown-ups see sense?

Myra makes a plan - 'Operation Home' - and is determined to make it succeed.
