Olga, Tatiana, Maria, and Anastasia. These are the daughters of Tsar Nicholas II, grand duchesses living a life steeped in tradition and privilege. The summer of 1914 is that precious last wink of time when they can still be sisters together, sisters that link arms and laugh, sisters that share their dreams and worries and flirt with the officers of their imperial yacht. But in a gunshot the future changes, for these sisters and for Russia. As World War I ignites across Europe, political unrest sweeps Russia. First dissent, then disorder, then revolution. For Olga, Tatiana, Maria and Anastasia, the end of their girlhood together is colliding with the end of more than they ever imagined.
