The Romanov Sisters
"They looked different, not like you or Anastasia now. And I remember there wasn't anyone named Alexandra among them."
"You are quite observant," Alex said. "Well, humans grow old and die, but vampires are different. They can't age or die, so they keep changing and evolving. The older we get, the better we look—and stronger, too. Now, you can say, I'm a very hot and sexy a-hundred-and-thirteen-year-old woman. Aren't you jealous?"
"Very," I said and rolled my eyes at her. "But how about the name?"
"After I was reborn, the priest named me after my mother," Alex said casually. "My former name is Marie Nikolevna Romanova."
