Olga, Tatiana, Maria and Anastasia Romanov led gilded but trapped lives in the palace of Tsarskoe Selo outside St Petersburg, seeing and knowing little of the outside world. In Four Sisters, historian Helen Rappaport tells the story of their short and ultimately tragic lives, over-shadowed by an unpopular father, a dominant mother and a haemophiliac brother, before their terrible assassination in 1918. The girls come alive in Helen's sympathetic but never sentimental biography, which is based on letters and diaries, eyewitness accounts and contemporary newspaper coverage and is full of telling details. Helen found writing Four Sisters an intense emotional experience, and it is easy to see why. This is a companion volume to her earlier best seller Ekaterinburg; The Last Days of the Romanovs.
