Stranger in Moscow

(please be mindful this is historic fiction and just a random idea i got)
Leaping from a makeshift cot built by the Bolsheviks and running into the dark woods of Yekaterinburg Russia, Maria Romanov, fourth daughter of the last Tsar of Russia finds herself on a train to her country's new capital of Moscow. Scared for her life, her future and what happens if the Bolsheviks find her she takes on the name of Mashka Alexandrovna, a combination of her nickname and her mothers name.
