Catching falling stars - Karen McCombie

It's 1940. Gloria and her little brother have been evacuated to the
countryside to get away from the dangers of the Blitz in London.
But their new home isn't as friendly as they'd hoped. The woman
they're living with, Miss Saunders, is strict, severe and an outcast
in the village. And the local children and other evacuees are
equally unwelcoming and mocking. But Gloria quickly learns that
nothing is ever as it seems in this strange new place. As possible
friends turn out to be enemies, and once sworn enemies might
be the best possible friends, Gloria finally realizes that believing
first impressions could mean missing out on the friendships that
can last a lifetime.
