The Romanov Sisters — Svetlana Ivanova

Not everything that dies stays dead. In the year 2054, the human race suffers the attack of the Other Ones. A global war marks the end of mankind. People are no longer free on earth. The ancient species force the remaining population into slavery. The survivors hide in fear of being captured and killed. Among them is Avery Pierce, a seventeen-year-old girl, who tries to escape her cruel fate. Yet one night they come for her. Captured and sold to a powerful royal house, she lives in a beautiful mansion where she has to serve her mistress. The problem is that there are two of them. Will she be treated as a mere slave or something else?
