Small acts of amazing courage

In 1919, independent-minded fifteen-year-old Rosalind lives in India with her English parents, and when they fear she has fallen in with some rebellious types who believe in Indian self-government, she is sent "home" to London, where she has never been before and where her older brother died, to stay with her two aunts. Her courage influences one of her aunts who longs for her own kind of independence.
