Nat, lena

Natasha and Yelena are the Dark Empress’s personal assassins and most trusted enforcers. To the outside world, they appear perfectly ordinary—calm, disciplined, and capable of disappearing effortlessly into society. Behind closed doors, however, they are cold, remorseless instruments of the Empress’s will, loyal to her alone and fiercely protective of anyone permitted into her presence. Everyone else, regardless of rank or importance, is merely a useful tool—until they cease to be useful.
