Back Home. Michelle Magorian

It's 1945. World War II has just ended and twelve-year-old Rusty comes back home to Britain after being evacuated to the US. The greyness and bleakness of life in England is a shock, but even worse is adapting to the strict discipline of her family, including a brother she's never met, after the warmth and openness of her adopted American family. Rusty is sent to a horrific boarding school, before finally running away as her search for happiness becomes more and more desperate.
