Super-heroic spies must unravel a conspiracy—and save the world—in this original Marvel adventure. Before Natasha Romanoff was an Avenger, she was a Russian spy and assassin, genetically altered by Soviet Union–era scientists to become a super soldier. But someone has stolen a sample of her blood—and the blood of James "Bucky" Barnes, the operative known as the Winter Soldier, another human weapon developed in a Russian laboratory. Whoever took their blood possesses the key to recreating the formula flowing through Natasha and Bucky''s veins—the formula that enhanced their physiology to superhuman levels. Now, the Black Widow and the Winter Soldier must work together to track down their mysterious enemy—even as their history as lab rats and conditioned agents brutally trained in Russia''s notorious Red Room continues to haunt them . . . Black Widow: Bad Blood is a collaborative novel by Lindsay Smith, Margaret Dunlap, Mikki Kendall, L.L. McKinney, and Taylor Stevens.
