It sounds rather nice.
A warm-hearted story with a theatrical background. Set in 1946 against the
aftershock of war, with rationing still in place and prisoners of war returning
home only to find their families almost strangers. Two such families join forces
to provide the summer concert party at a seaside holiday camp. Hidden talents
emerge, romances struggle and blossom and jealousies and artistic temperament
are overcome as the families find happiness once more. "Peace was creeping back
into the world, and into the heart."
They are also republishing the adult book Lady of Letters, by Josephine Elder, who is one of my favorite authors of English school stories for girls. I've read this one, and it's interesting, although not as good as her children's books!
