July, 1941. Rosina Raja is half-Indian and half-English. She has always lived in India, so when her mother passes away and she moves to England (where it rains all the time) she is miserable and doesn't have any friends. Life changes dramatically for Rosie when she discovers that her army captain father is actually a spy for the British government. She can't bear to be left behind so she stows away in his plane. Finding herself in occupied France, Rosie is soon drawn into the struggle against the Nazis. With new allies and new enemies at every turn, she must help her father complete his mission, and more importantly, make sure they both get home alive.
