You definitely have heard the true story of the Romanovs, the last Russian imperial family who were overthrown and eventually murdered by the Bolshevik regime. You definitely have heard of Anastasia, the youngest grand duchess who was the subject of survival rumours (plus an animated movie and a Broadway musical) for decades. But you might not have heard of the other woman whose story inspired Ariel Lawhon's I Was Anastasia: Anna Anderson, the Polish factory worker who was the most credible and famous Anastasia impostor. Throughout the novel, which flashes back between Anastasia's life in the revolution and the present-day narrator's attempts to regain her memories, the mystery persists as to whether the narrator is actually royalty or just a madwoman.
