The Secret Letters of Gertie and Hen

We live the second world war through the eyes of two ten-year-old pen friends who find themselves caught in the political crossfire. Gertie lives with her mother, father and two sisters in Berlin, whilst Hen resides in Balham, London, with her parents and younger brother. Though now enemies by association, the girls struggle to remember their friendship from before the war, and continue to write to one another throughout their time of need.
